This PR adds PhpStan. Currently only with level 3, but might rise that in the future.
Beside, this PR lets both PhpStan and Psalm run under PHP 8.0 (before, Psalm was running with PHP 7.4). This works by upgrading the upstream workflows to 1.3.0, see https://github.com/doctrine/.github/pull/27 for further information.
