Better GitHub Co-Authors

Adds a button to GitHub pull requests to make it simple to add co-author credits for all PR participants before merging.

This extension makes it easier to add co-author credit to PRs on GitHub. It adds an “Add Co-authors” button to GitHub’s PR merge UI which automatically collects all participants in the current PR, generates “Co-authored-by” comments for the users, and adds them to the commit message. This means you can credit PR reviewers and commenters in the commit history and not only code contributors.
