feat: allow PHPUnit 10

allow "spatie/phpunit-snapshot-assertions" 5

PHPUnit 11 support could be provided with a seperate configuration file with the migrated configuration.
CI needs to be adjusted to read the correct file.
I think it is not worth the effort right now.

Is there actually any reason to not rely on PHPUnit 11 specifically and ignore all older versions? This is a dev dependency afterall.

[Chris53897]

The lowest supported PHP Version is 7.1 "php": "^7.1 || ^8.0",
We need to support PHPUnit 7 until the PHP Min Version is bumped.

Ah yeah, that makes sense. I wonder if it's safe by now to drop PHP 7 (and 8.0), since those have been EOL for some time. Of course, that'd mean bumping our major version to 3.

[Chris53897]

I am in favor of dropping older PHP versions. Min Version PHP ^8.1 ?

Do your want to work on this, or should i?

Feel free to go ahead!
