Reviews:
user: login: gemini-code-assist[bot]
body: Hello @purelind, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

## Summary of Changes
This pull request introduces a new Tekton task and trigger template to automate the process of updating the `go.mod` file and LDAP certificate/key in hotfix branches for specific release series (7.5, 8.1, and 8.5). The new task `create-pr-to-update-gomod-fix-ladp` replaces the appdash dependencies and updates the `go.mod` file. Additionally, it checks if the target branch is a hotfix branch for the specified releases. If so, it cherry-picks a specific commit from the base release branch to update the LDAP certificate and key. The corresponding TriggerTemplate `update-pingcap-tidb-gomod-fix-ladp-for-hotfix-branch` facilitates the execution of the task.

### Highlights
* **New Tekton Task**: Introduces `create-pr-to-update-gomod-fix-ladp` task to automate `go.mod` updates and LDAP certificate/key updates in hotfix branches.
* **New Trigger Template**: Adds `update-pingcap-tidb-gomod-fix-ladp-for-hotfix-branch` TriggerTemplate to trigger the new task.
* **LDAP Certificate Update Automation**: Automates the process of cherry-picking a specific commit from the base release branch to update the LDAP certificate and key in hotfix branches for releases 7.5, 8.1, and 8.5.

### Changelog

body: ## Code Review
This pull request introduces a new Tekton task and trigger template to automate LDAP certificate updates for hotfix branches. The changes look good overall, but there are a few areas that could be improved for clarity and efficiency.

### Summary of Findings
* **Conditional Logic Clarity**: The nested `if` statements for determining the `base_release_branch` can be simplified for better readability and maintainability.
* **Error Handling**: Consider adding more robust error handling, especially around the `git fetch` and `git cherry-pick` commands, to ensure the task doesn't fail silently.
* **Task and Trigger Names**: The names of the task and trigger are quite long. Consider if they can be shortened while still being descriptive.

### Merge Readiness
The pull request is almost ready for merging. Addressing the comments regarding conditional logic, error handling, and potentially shortening the task and trigger names would improve the overall quality and robustness of the changes. I am unable to approve this pull request, and recommend that others review and approve this code before merging.

Consider adding error handling to the `git fetch` command. If the fetch fails, the task should exit with an error message instead of continuing. This will prevent unexpected behavior if the base release branch doesn't exist.

```
            git fetch origin $base_release_branch || { echo "Failed to fetch $base_release_branch"; exit 1; }
```

Similar to the `git fetch` command, add error handling to the `git cherry-pick` command. If the cherry-pick fails (e.g., due to conflicts), the task should exit with an appropriate error message.

```
            git cherry-pick $commit_to_cherry_pick || { echo "Failed to cherry-pick commit $commit_to_cherry_pick from $base_release_branch"; exit 1; }

**Summary:** 

This PR introduces a new Tekton task `create-pr-to-update-gomod-fix-ladp` and a corresponding TriggerTemplate `update-pingcap-tidb-gomod-fix-ladp-for-hotfix-branch` to automate handling LDAP certificate updates for specific hotfix branches. The task is designed to automatically create a pull request to fix the `go.mod` file and update the LDAP certificate and key for hotfix branches (v7.5, v8.1, v8.5). The code quality of this PR seems good overall, but there are some minor improvements that can be addressed.

**Code Improvements:**

- In the `create-pr-to-update-gomod-fix-ladp.yaml` file, the checks for whether the branch needs an LDAP fix are repeated. This could be refactored into a function to adhere to the DRY principle. 

- In the `create-pr-to-update-gomod-fix-ladp.yaml` file, there's a hard-coded reference to the base release branches. These could be moved to a configuration or environment variable to make the code more maintainable.

**Best Practices:**

- In the `create-pr-to-update-gomod-fix-ladp.yaml` file, there are several echo statements used for debugging. These should be replaced with proper logging statements that provide more context for easier debugging.

- In the `create-pr-to-update-gomod-fix-ladp.yaml` file, there's no error handling for the case when the `gh` tool is not installed. This can lead to a failure without a clear error message.

- In the `create-pr-to-update-gomod-fix-ladp.yaml` file, the naming of the variable `needs_ldap_fix` can be improved to `does_need_ldap_fix` or `should_update_ldap` for better readability. 

- There seems to be a lack of comments in the code explaining what each section is doing. Adding these comments can improve the readability of the code.

- The test coverage of this PR is not clear. It would be beneficial to add tests to ensure that the new task and trigger template work as expected.

Here are some code suggestions:

```diff
-        needs_ldap_fix=false
+        does_need_ldap_fix=false

-        if [ "$needs_ldap_fix" = "true" ] && [ -n "$base_release_branch" ]; then
+        if [ "$does_need_ldap_fix" = "true" ] && [ -n "$base_release_branch" ]; then

-        if [ "$needs_ldap_fix" = "true" ]; then
+        if [ "$does_need_ldap_fix" = "true" ]; then

-        type -p curl >/dev/null || ( apt update &&  apt install curl -y)
+        type -p curl >/dev/null || { echo "curl is not installed"; exit 1; }

-        # Fetch the latest state of the remote branch to accurately compare

**Summary:**
This pull request introduces a new Tekton task named `create-pr-to-update-gomod-fix-ladp` to automate LDAP certificate updates for specific hotfix branches. The task involves steps like cloning the repository, updating the LDAP certificate and key if the branch is a hotfix branch, updating the go.mod file, and creating a pull request if necessary. A corresponding TriggerTemplate `update-pingcap-tidb-gomod-fix-ladp-for-hotfix-branch` is also added to facilitate the execution of the task with specified parameters. The overall implementation seems to be in good shape.

1. **Code Improvements:**

    - File: `apps/prod/tekton/configs/tasks/hotfix/create-pr-to-update-gomod-fix-ladp.yaml`
    
    - Line: 112-118
        - Why it's an issue: The curl command might fail due to network issues or GitHub CLI download link changes.
        - Suggested solution: Add error handling for `curl` command to ensure `gh` tool is installed correctly. Also, consider adding retries for network-related failures.
        
        ```diff
        + type -p curl >/dev/null || ( apt update &&  apt install curl -y)
        + for i in {1..3}; do # retry 3 times
        +   curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg |  dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg \
            && chmod go+r /usr/share/keyrings/githubcli-archive-keyring.gpg \
            && echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" |  tee /etc/apt/sources.list.d/github-cli.list > /dev/null \
            && apt update \
            && apt install gh -y && break || sleep 5; done
        + [ $(gh --version) ] || { echo 'gh installation failed'; exit 1; }
        ```
        
2. **Best Practices:**

    - File: `apps/prod/tekton/configs/tasks/hotfix/create-pr-to-update-gomod-fix-ladp.yaml`
    - Line: 60-102
        - Why it's an issue: The script block does not have clear comments explaining the logic behind the LDAP update process.
        - Suggested solution: Add meaningful comments to explain the logic behind cherry-picking a specific commit and the conditions to update the LDAP crt/key.

3. **Testing coverage gaps:**
    
    - There are no visible changes or additions to tests in the PR. Ensure that the new logic for updating LDAP certificates and creating PR is covered by tests. 

Please address these issues and update the PR for further review.

**Summary:**
The PR introduces a new task `create-pr-to-update-gomod-fix-ladp` and its corresponding trigger template `update-pingcap-tidb-gomod-fix-ladp-for-hotfix-branch` to automate the process of handling LDAP certificate updates for specific hotfix branches. It achieves this by replacing the existing `create-pr-to-fix-gomod` task. The changes are well-structured and appear to follow good practices. However, there are some areas of improvement, particularly in regard to error handling and code duplication.

1. **Code Improvements:**
   - There are multiple places where the code checks if a branch requires LDAP fixes. This leads to code duplication and could be refactored into a function.
     - File: create-pr-to-update-gomod-fix-ladp.yaml
     - Lines: 32-53
     - Suggested solution:
       ```yaml
       does_hotfix_release_need_ldap_fix() {
         case "$1" in
           release-7.5-*) return 0 ;;
           release-8.1-*) return 0 ;;
           release-8.5-*) return 0 ;;
           *) return 1 ;;
         esac
       }
       ```
   - The script doesn't handle potential failure of the `git clone` operation. This could lead to subsequent steps operating on a non-existent directory.

     - Suggested solution: Use a conditional to check the exit status of the `git clone` operation before proceeding.
       ```yaml
       git clone $(params.git-url) --branch $(params.branch) --depth 1 /workspace/src || exit 1
       ```

2. **Best Practices:**
   - The commit messages could be more descriptive to provide better context about the changes.
     - File: create-pr-to-update-gomod-fix-ladp.yaml
     - Lines: 146, 172
     - Suggested solution: Include more information about the changes in the commit messages. For example, "Update 'sourcegraph.com/sourcegraph/appdash*' in go.mod and fix LDAP crt/key for hotfix branches".
   - The code could benefit from additional documentation, particularly around the logic determining whether a branch is a hotfix branch for a specific release series.
     - File: create-pr-to-update-gomod-fix-ladp.yaml
     - Lines: 32-53
     - Suggested solution: Add comments to explain the rationale behind the branch name checks and how it determines whether LDAP fixes are necessary.

**Summary:**
The PR introduces a new Tekton task `create-pr-to-update-gomod-fix-ladp` and a corresponding TriggerTemplate `update-pingcap-tidb-gomod-fix-ladp-for-hotfix-branch`. This new task and trigger template are designed to automate handling LDAP certificate updates for specific hotfix branches (v7.5, v8.1, and v8.5). The task includes steps to clone the branch, update the LDAP certificate and key, update the `go.mod` file, and create a PR if necessary. The overall quality of the PR is good, but there are a few improvements that can be made.

**Code Improvements:**

- The `create-pr-to-update-gomod-fix-ladp` task seems to have a debug name in the metadata, which may have been left by mistake.
  - File: `create-pr-to-update-gomod-fix-ladp.yaml`
  - Line: `metadata.name` 
  - Suggestion: Change the task name to `create-pr-to-update-gomod-fix-ladp` from `create-pr-to-update-gomod-fix-ladp-debug-by-wulifu`.

- The `create-pr-to-update-gomod-fix-ladp` task should handle errors that may occur during the execution of the shell scripts in its steps. Currently, if an error occurs, the task will continue to execute, which may lead to unexpected behaviors.
  - File: `create-pr-to-update-gomod-fix-ladp.yaml`
  - Lines: All script sections in every `steps` item.
  - Suggestion: Add `set -e` at the beginning of each script to cause the script to exit on a failure.

**Best Practices:**

- The `create-pr-to-update-gomod-fix-ladp` task has a lot of complex logic in shell scripts. This makes the task hard to understand and maintain. A better practice could be to encapsulate this logic in a script file or a custom Docker image.
  - File: `create-pr-to-update-gomod-fix-ladp.yaml`
  - Lines: All script sections in every `steps` item.
  - Suggestion: Consider moving the shell scripts into a separate script file or Docker image.

- The `create-pr-to-update-gomod-fix-ladp` task lacks comments explaining what each step does. Adding meaningful comments can make the task easier to understand and maintain.
  - File: `create-pr-to-update-gomod-fix-ladp.yaml`
  - Lines: All script sections in every `steps` item.
  - Suggestion: Add comments to each step to explain what it does.

- The PR lacks tests to ensure that the new Tekton task and TriggerTemplate work as expected.
  - Suggestion: Add tests to verify the behavior of the new task and TriggerTemplate.
