fix(psalm): Enforce that psalm is executed against the minimum PHP version

[nickvergessen]

As discussed the other day with @st3iny

@st3iny

Sounds good, but psalm will probably take some more time: vimeo/psalm#11107

@nickvergessen

https://github.com/nextcloud/spreed/actions/runs/11930485130/job/33251359582 talk psalm works on 8.4
it doesnt have a hardcoded version check breaking it
might of course depend on edge cases your code triggers
but I would think Talk is pretty edgy

@st3iny

There are some deprecation warnings and it broke in one of my maintained apps though
Can't remember which one

@nickvergessen

the other fix for psalm is making sure you have the correct base version
https://github.com/nextcloud/spreed/blob/main/psalm.xml#L8
otherwise it checks your code to only be compatible with the actually used php version
instead of the minimum
we should add a grep call to the ci workflow, to make sure the phpversion is added

• 🔴 test: Break version enforcement files_retention#679
