CI: skip ut-a5 while the a5 runner is under repair

[ChaoZheng109]

The a5 self-hosted runner is out for repair, so ut-a5 has no host to run on and sits waiting for one instead of reporting a result. This short-circuits its existing gate with false && so it reports skipped, mirroring exactly what #1481 already did for st-onboard-a5 on the same runner.

Nothing declares needs: ut-a5 and main has no required status checks, so the job's absence blocks no merge. Coverage for a5 changes falls back to st-sim-a5, which runs on GitHub-hosted runners.

To re-enable once the runner returns: drop the false && from the if: gate (same as the note left on st-onboard-a5).

Poem

A tiny false guards the gate,
So ut-a5 must now wait.
The rabbit checks the workflow run,
And finds the job has come undone.
“Hopfully next time, little test!”
