Better git logic for updating contributors in readme

[mrubens]

Important

Improves GitHub Actions workflow to update contributors in README by consolidating steps and refining change detection and commit logic.

• Workflow Changes:
  • Consolidates update-contributors and change-checking into a single step in update-contributors.yml.
  • Uses git diff --quiet to check for changes in README.md.
  • Removes separate change-checking step.
• Commit Logic:
  • Stages and commits changes only if README.md is modified.
  • Configures git user for commit as github-actions[bot].
• Pull Request Creation:
  • Creates a pull request only if changes are detected.
  • Uses peter-evans/create-pull-request@v5 to automate PR creation.
