Add conditional `@implements` tag to Doctrine repository template

Adding the `@implements` phpdoc tag on generated Doctrine repository classes will help IDE and prevent tools like phpstan from generating errors.

`@implements` is only added if `$with_password_upgrade` is set to true, avoiding useless phpdocs.

Similar to #1088
