ci: add tests for PHP 8.5

[Chris53897]

as nigthly now addresses PHP 8.6, this will add tests for PHP 8.5

[Chris53897]

Failing tests on lower PHP versions. Should be fixed in a sperate PR.

[maennchen]

The tests are fixed (#390 & #391).

The version bump is currently incomplete. It also needs to be switched in the windows / mac job and in the .tool-versions.

It looks like we'll have to wait for Psalm support for PHP 8.5. Right now the dependencies can't be resolved.

[Chris53897]

I added a line to remove psalm for this run, as there is a sperate run on PHP 8.3 with psalm.
But tests are slow. PHP 8.5 ond windows still running. Maybe because of code-coverage with xdebug instead of pcov?

The tests run some very big files. That's unfortunately just slow and there's not much we can do about that. (To test Zip64 properly we need files > 4Gb) That's also why some tests have a slow tag to exclude them for local development.

Running Psalm on 5.3 and not latest was actually an oversight. I switched to use the .tool-versions in #392

Until Psalm has 8.5 compatibility, I'll keep this PR open. I don't want stuff like the composer remove in the actions and I don't see a problem waiting a few more days until our dependencies have caught up.

[Chris53897]

ok, lets wait for psalm 6

@maennchen Ready for review
