ci: pin setup-php to avoid a regression

[blizzz]

Temporarily, until shivammathur/setup-php#743 is solved.

Those files are not (at least not all 😅) distributed via our workflow-templates.

/backport to stable27

[blizzz]

/backport to stable26

[blizzz]

/backport to stable25

Lint php-cs apparently alao needs a pinning...

[szaimen]

Apparently shivammathur/setup-php#743 is now already fixed

[solracsf]

Fixed at https://github.com/shivammathur/setup-php/releases/tag/2.25.4

We still should pin as security measure.
We're doing it in the templates too

[szaimen]

So merge?
