`> test-mute` label doesn't trigger precommit checks

Instead it only seems to trigger es-docs tests. See

#49479
#49476

Actually this seems to be going on for a while, i.e.

#49364
#48535

The last PR with this label that ran precommit as far as I can see is #44159 on July 10.

Duplicates #48505 I think.
