Bug Report

Summary

I have a entity with a read-only id property, and when a try to remove the entry a receive a LogicException. Attempting to change readonly property App\Entity\Supplier::$id.

Current behavior

The UnitOfWork always try to set the id of entity to null when it' executes the executeDeletions method.

How to reproduce

#[ORM\Entity]
class Supplier
{
    #[ORM\Id]
    #[ORM\Column(name: 'id', type: 'integer', nullable: false)]
    #[ORM\GeneratedValue(strategy: 'AUTO')]
    public readonly int $id;

    public function __construct(
        #[ORM\Column(nullable: false)]
        public readonly string $name,
    ) {}
}

$entityManager->find(Supplier::class, 1);
$entityManager->remove($entity);
$entityManager->flush($entity);

Expected behavior

Delete the entry from database, but i dont know what's the expected behavior to the orm internals.
