Feature release (minor)

Changed

• Upgraded to doctrine/doctrine-module ^6.2.0, see release notes
• doctrine/cache ^2 is now required (1.x is not supported anymore) - Note: This change implies that laminas-cache is now used for caching, as doctrine/cache v2 does not contain implementations anymore. Using laminas-cache, however, is the default config since the 6.0.0 release. If you are using other adapters than array and filesystem, you might need to require additional laminas packages!
• doctrine/dbal 3.x is now required (2.x not supported anymore)

Removed

• Support for PHP 8.0
