Adds the shared PR size check from TF-Minecraft/TLibs#39. It labels pull requests size:XS to size:XXL and, from size:L, requires an approval from someone other than the author. See Pull request size.

After this merges, the ruleset requires the "PR size" check instead of one approval on every pull request.

Merge Risk: 🔵 Low · up to 60841

Changing a pull request's base branch will not recompute its size label or approval requirement until a new commit is pushed. Adding the edited event type is a small fix and the risk is low.

Run the size check when the pull request’s base changes.

If someone changes the base branch, the merge-base diff can change without a new head commit. This workflow does not handle pull_request.edited, so the size label and check result can remain based on the old base. Add edited to the event types. (raw.githubusercontent.com)
