[Github] Filter only origin branches in prune unused branches workflow

boomanaiden154 · web-flow · commit d698b3a0670b · 2026-01-28T14:28:29.000-10:00
We should only have branches from the origin remote when actually running the workflow, but this makes the script easier to test locally where I have branches from several different remotes. Reviewers: Pull Request: llvm#178540
