This would be helpful for repos that have scheduled jobs w/ release/* as a branch trigger - since devs can't delete internal release branches, those pipelines are doing a bunch of pointless work on stale preview branches. e.g:

Yep agreed this would be good. This would be:

Delete the internal branch

We might want to initially add more checking..only delete if the head SHA of the branch is tagged.
