updateDataObject is only partially async

[cancan101]

updateDataObject makes blocking calls to the (external) search provider.

updateData is async:

generic-data-index-bundle/src/EventSubscriber/DataObjectIndexUpdateSubscriber.php

Lines 106 to 119 in 159caeb

	$dataObject = $event->getObject();
	Service::useInheritedValues(true, fn () =>
	$this->indexQueueService
	->updateIndexQueue(
	$dataObject,
	IndexQueueOperation::UPDATE->value,
	$this->synchronousProcessing->isEnabled(),
	$dataObject->hasChildren(includingUnpublished: true),
	$this->synchronousProcessingRelatedIds->isEnabled() === false
	)
	->commit()
	);
	$this->queueMessagesDispatcher->dispatchQueueMessages();

but updateSiblings is not:

generic-data-index-bundle/src/Service/SearchIndex/IndexElementIndexService.php

Line 51 in 159caeb

if ($newIndex === $this->getIndexedIndex($element)

this can cause significant slowdowns with object updates, especially for large folders.
