What is the current behavior?

Issue Number: #671

Turns out what:

Yes, git log -1 --format=%H should be equal to github.sha in the CI runtime if you're running the workflow on the same commit. However, there are a few scenarios where they might not match:

• Pull Request workflows: GitHub creates a merge commit by merging your branch with the target branch. In this case:
  • Your local: your-branch-commit
  • GitHub Actions: temporary-merge-commit

What is the new behavior?

The new behavior ensures that the commit SHA is consistent across different GitHub Actions workflows. This addresses scenarios in pull request workflows where GitHub creates a temporary merge commit, causing discrepancies between the local branch commit SHA and the one used in the GitHub Actions environment. As a result, the commit SHA will now reliably match between the local branch and the CI runtime, preventing inconsistencies and potential issues in the workflows.
