revert: "ci: Skip Java checks if only docs have changed" (deephaven#7193)

Reverts deephaven#7187

These are still required checks, and by skipping these steps the PR will
always be pending and blocked from merging. E.g.
deephaven#7171
<img width="962" height="434" alt="image"
src="https://github.com/user-attachments/assets/12134bea-4abb-4925-a17d-95a4b20a1041"
/>

So we still need to report the status as "done", just while skipping the
work... there's a discussion on GitHub around this:
https://github.com/orgs/community/discussions/44490

I'll look into the best solution, for now I'm reverting to allow PRs to
be able to merge again.
