Subject: [PATCH 3/3] CI: Deploy concurrency and path filtering for Action
 activation

Reduce unnecessary churn by skipping CI Action for documentation-only
changes.

Also, avoid duplicate Actions on pushes to PR branches (which trigger
both the `push` and `pull_request` events).

Finally, cancel earlier Actions still running when a non-main branch is
updated, as these are usually unneeded, and the superceded Action can even
cause spurious failures after a subsequent force push orphans the source commit.
