Issue:
Fix the first contributor filter
### Is there an existing issue for this?

- [X] I have searched the existing issues

### Description of the bug

In the following scenario:

1. User foo contributes for the first time.
2. New release is created and changelog is generated.
3. User foo contributes after the release.
4. New release is created and changelog is generated BUT user foo is removed from the first contributors section from the previous release.

Might be related to #825 

### Steps To Reproduce

See above.

### Expected behavior

This happens due to **not checking** the dates of the new commits while updating the release metadata.

https://github.com/orhun/git-cliff/blob/8d10edb7450aaf189fbce5f78a72274739f73ba9/git-cliff-core/src/remote/mod.rs#L337-L347

Here, we check all the commits, but you see, in the new release user foo already contributed, so his contribution is not marked as first time anymore.

To fix it, we should simply:

```patch
diff --git a/git-cliff-core/src/remote/mod.rs b/git-cliff-core/src/remote/mod.rs
index 77d14e7..32e61a9 100644

```

Apply the patch above and you will see that we are missing the implementation for GitHub, GitLab, etc. We need to check each remote and add the appropriate field for serializing the timestamp from their API response.
