Look for all `<current_name>` occurences in the code and replace them with the new branch name. Create a pull request for review

There is no simple way to avoid false positives, but there are several places where the current branch name needs to be replaced:

• README badges
• CI configurations: GitHub Actions, Travis, CircleCI, etc
• Contributing docs

I think I'd use GitHub's code search API and search for the terms

• <current_name>
• branch%3A<current_name>

The search does not seem to find all occurrences, but it does find all files with at least on occurrence, which is good enough for us.
