Qual: pre-commit: run phpcs on all files in 'main' branches. (#28018) (#28067)

This change to the workflow will run phpcs on all files in develop,
17.0, 18.0, ... (rule== branch ends in .0).

This ensures that phpcs is run in a github workflow for fast phpcs
issue detection in the develop and other main branches.

Ultimately, this means that the PHPCS action can be disabled
in branches where it is active.  But I propose to verify that
the updated action does the job as expected (tested in a fork
it is ok).
