Add possbility to return Entity from `delete<...>ById(id: MyId)` method

[ars-java]

I try to use derived delete method to get deleted entity after deleting, but every of such signatures

fun removeMyEntityById(id: MyId): Optional<MyEntity>
fun removeMyEntityById(id: MyId): MyEntity?
fun deleteMyEntityById(id: MyId): Optional<MyEntity>
fun deleteMyEntityById(id: MyId): MyEntity?

throws

class java.lang.Integer cannot be cast to class ...MyEntity (java.lang.Integer is in module java.base of loader 'bootstrap'; MyEntity is in unnamed module of loader org.springframework.boot.devtools.restart.classloader.RestartClassLoader @50f8f031)

Every time Spring JPA returns count of deleted entities.

Default implementation of deleteById in SimpleJpaRepository use findById to select deleting entity but doesn't return it too.

	@Override
	@Transactional
	public void deleteById(ID id) {

		Assert.notNull(id, ID_MUST_NOT_BE_NULL);

		findById(id).ifPresent(this::delete);
	}

I think that it will be good if we can use such signatures to return entity removed by Id
