rector: [SOLID] Rector\SOLID\Rector\Class_\FinalizeClassesWithoutChildrenRector: should not change Doctrine Entities

When using the level solid, it will turn every non-final class to final, including Doctrine entities. But as stated in Doctrine’s documentation :

An entity is a lightweight, persistent domain object. An entity can be any regular PHP class observing the following restrictions: - An entity class must not be final or contain final methods.

So it would be nice if there was a way for Rector to detect @ORM\Entity annotation and not process these classes.
