@trask Will be approving after the `rc` case has been confirmed to work.

@trask I'm testing this in my local repository. For the two PRs that are generated from `prepare-release-branch` workflow, for the second pr that updates the version in main from `1.12.0rc2-dev`...

@trask Just to verify, I performed the `prepare-release-branch` workflow one more time after the previous run above, and the first PR that merges into the release branch changes the version...
