Subject: [PATCH 1/2] Move setup-java to v5 and enable Gradle's build cache

- setup-java v4 is deprecated; use v5 (still with `cache: gradle`,
  which works once job containers can reach the runner's cache server).
- Enable Gradle's build cache (org.gradle.caching) so unchanged
  compilations are restored from cache instead of re-run.

Subject: [PATCH 2/2] Run the compile check on pull requests only, not on
 merges

A merge to master re-ran the same compile the PR had just done. Keep
the pull_request trigger and drop the push-to-master one.
