Greptile Summary

This PR fixes the dst refspec main matches more than one push failure in the Update Contributors workflow by replacing the ambiguous HEAD:${GITHUB_REF_NAME} refspec with the explicit HEAD:refs/heads/${GITHUB_REF_NAME} for both the git pull --rebase and git push commands. The fix is targeted and correct — it eliminates the ambiguity that arises when a tag named main coexists with the main branch.

Confidence Score: 5/5

Safe to merge — the change is a minimal, correct fix with no regressions.

Both changed lines correctly apply the refs/heads/ prefix, directly resolving the documented ambiguity. No logic is altered, no new risk is introduced, and the fix matches Git's documented behaviour for disambiguating branch vs. tag refspecs.

No files require special attention.
