On the translation page: https://symfony.com/doc/current/translation.html#translations-of-doctrine-entities two package are suggested for entities translation: Gedmo\DoctrineExtension and KnpLabs/DoctrineBehavior. But the second package doesn't support Symfony 7 and Doctrine 3, since the documentation is supposed to give suggestions for the latest Symfony version i think those packages should not be there. They will work fine on Symfony 6 but on SF7 many downgrades should be done.
