[mediawiki/core@REL1_39] Respond to some messages from Phan on PHP 8.1

https://gerrit.wikimedia.org/r/875925

Job mediawiki-core-php81-phan-docker is not running under experimental in REL1_39, because it is voting on master. It is possible to have experimental on release base to have that job as additional run?

It does run under check php... Is that enough? Do we need it experimental too?

That is enough. Having release queues for the other checks is overkill. The "run as part of gate-and-submit" is not exact for the releases, but okay to live with.

It passed now, the challenge here was the moved code and classes between REL1_39 and REL1_40 (current master), all the great work between the release cut and the phan fixes.
With T166010 that makes the next releases not easier to manage, hopefully gerrit can follow many of the moved files in the future.

It is planned to make the phan-php81-job voting on REL1_39?
