ContentUn/PublishTaskHandler requires entityRepository to implement ObjectRepository

[Prokyonn]

Problem:

The ContentPublishTaskHandler and the ContentUnpublishTaskHandler get the entityRepository via the entityManager with $repository = $this->entityManager->getRepository($class);.

In the doctrine/DotrineBundle the method ContainerRepositoryFactory::getOrCreateRepository(..), which is used by the EntityManager::getRepository(..) method, is type hinted for versions newer than 2.0.6 with the return type ObjectRepository.

Thus means, for the ContentTaskHandler to work properly, the entityRepository must implement the ObjectRepository interface.

Possible solution:

Instead of getting the repository via the entityManager, just use entityManager->find($class, $id).

Would implement this similar to the ContentReindexProvider/ContentTeaserProvider/ContentObjectProvider/...:

$this->entityManager->createQueryBuilder()->from($this->contentRichEntityClass, 'contentRichEntity')

Want to mention that ContentReindexProvider/ContentTeaserProvider/ContentObjectProvider are currently violeting the #196.

There already exist the DimensionRepository which should be used for all admin processes. The DimensionRepositoryInterface should be adjusted to get just the class and the id of the element (more is currently not needed):

    public function load(
        string $contentRichEntityClass,
        string|int $identifier,
        array $dimensionAttributes
    ): DimensionContentCollectionInterface {

SuluContentBundle/Content/Infrastructure/Doctrine/DimensionContentRepository.php

Lines 46 to 49 in bd6674a

	public function load(
	ContentRichEntityInterface $contentRichEntity,
	array $dimensionAttributes
	): DimensionContentCollectionInterface {
