Code Review

This pull request correctly removes the use of a forked Keystone repository, as the required bug fix is now in the upstream release. The change itself is just a removal of the source override in etc/kayobe/kolla.yml. While the change is correct, I've suggested adding a release note to properly document this dependency update for users, similar to how other such changes have been handled in this project.

etc/kayobe/kolla.yml (138-141)

While removing this forked repository is the correct action, this change should be accompanied by a release note to ensure users are aware of the update. A similar change for Magnum included one (see releasenotes/notes/use-upstream-magnum-86854beee69151f5.yaml). Please consider adding a release note for this change.
