[Turbo] Doesn't work with entity that uses composite primary key

[chapterjason]

I noticed it is not possible to use an entity with a composite primary key for broadcasting.

It looks like instead of the id array which must be Stringable, the whole entity is returned and $id is something like [instanceof ClassA, instanceof ClassB]:

ux/src/Turbo/src/Doctrine/BroadcastListener.php

Lines 150 to 153 in 8db386c

	$id = $em->getClassMetadata($class)->getIdentifierValues($entity);
	foreach ($options as $k => $option) {
	$options[$k]['id'] = $id;
	}

This will result in the appended exception here:

ux/src/Turbo/src/Broadcaster/TwigBroadcaster.php

Line 66 in 8db386c

'id' => implode('-', (array) ($options['id'] ?? [])),

In TwigBroadcaster.php line 66:
