Multiple build runs from the same PR don't seem to be getting canceled. There's a suspicious line break in the `concurrency` option which might be confusing GitHub and causing this. cf. [#mathlib4 > github action bandwidth @ 💬](https://leanprover.zulipchat.com/#narrow/channel/287929-mathlib4/topic/github.20action.20bandwidth/near/547550820).

The issue (as [explained to me by Claude](https://claude.ai/share/9880d667-ff16-455f-b875-b273558d5256)) is apparently that `github.ref` for workflows triggered by `pull_request_target` is always `refs/heads/master`, so they all end up getting unique concurrency groups. I also add a step to print some build info to the logs, on the off chance that this still doesn't fix things. Follow-up to #31032 which was only a partial fix.

I also add a step that ends up putting some build info in the logs, on the off chance that this still doesn't fix things. (Strictly speaking we don't log the data, we just put them in the env vars so that they are visible by expanding the "Run ..." details.) Follow-up to #31032 which was only a partial fix.
