Support Doctrine/ORM 3.x & PHP 8.2

[Lpsd]

All other support is dropped, minimum Doctrine 3.x, Symfony 7, PHP 8.2.

• Removes annotations
• Use Doctrine listener instead of subscriber
  • EncryptEventSubscriber => EncryptEventListener
  • DoctrineEncryptSubscriber => DoctrineEncryptListener
  • subscriber_class => listener_class

Tested lightly, appears to be working fine.

Resolves #57 #55 #50
