## Description

This PR allows skipping CI checks for [ignored files](https://github.com/juspay/orca/blob/5593a97c91e347a36b21bf78cf1f91d3ae5a946d/.github/workflows/CI.yml#L20-L30).

This adds a workflow file with the same workflow and job names to simply return true for all checks. Even though this feels like a workaround, this is recommended by GitHub on their docs [here](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/troubleshooting-required-status-checks#handling-skipped-but-required-checks).

One of the PRs affected by this behavior is #9, as it's CI checks are stuck on a pending state.

## Description

This PR fixes a minor derp introduced in #10. Turns out specifying `runs-on: ubuntu-latest` vs. specifying `runs-on: ${{ matrix.os }}` with a single `ubuntu-latest` entry causes GitHub to consider them as different jobs, and thus do not count towards required status checks.
