moved this case into the loose-comparison-* files, as it depends on php version

I think we have a new todo for PHPStan 3.x: adjust all Type methods which depend on PhpVersion and turn them into using PhpVersions

Yeah, this should be possible. It's possible to make PhpVersions from PhpVersion (without losing precision), but not vice-versa.
So places that only have PhpVersion could still call these methods by transforming it into PhpVersions first.
