[feat] Mercure doesn't use state provider when publishing updates

[divine]

API Platform version(s) affected: 4.1.7

Description
Mercure doesn't use entity's state provider when publishing updates

How to reproduce

Let's say you've this in your operations:

new Get(
    provider: ExampleProvider::class,
),

and your ExampleProvider returns a calculated field or extra data from another database.

Mercure publish update listener simply doesn't take into account entity's provider.

Possible Solution

Looks like it's only supports seriliazer:

core/src/Symfony/Doctrine/EventListener/PublishMercureUpdatesListener.php

Lines 242 to 249 in f48a2be

	$resourceClass = $this->getObjectClass($object);
	$context = $options['normalization_context'] ?? $this->resourceMetadataFactory->create($resourceClass)->getOperation()->getNormalizationContext() ?? [];
	// We need to evaluate it here, because in storeObjectToPublish() the resource would not have been persisted yet
	$this->evaluateTopics($options, $object);
	$iri = $options['topics'] ?? $this->iriConverter->getIriFromResource($object, UrlGeneratorInterface::ABS_URL);
	$data = $options['data'] ?? $this->serializer->serialize($object, key($this->formats), $context);
