This PR skips all tests on php 8 that would trigger an autoload on DBAL's `PDOConnection`. Those tests would exit with a fatal error because of incompatible method signatures (see doctrine/dbal#3791) and until we can test against a compatible version of DBAL, there's (at least from my point of view) nothing we can do about it. Once this issue is resolved, we can revert this change.
