Hmm... the LazyChoiceLoader is only available in Symfony 7.2 :|

What do we do ? Revert (but then the deprecation is a bit strange to be honest...) or bump requirements ?

In the deprecation we mentioned to use the Symfony\Component\Form\ChoiceList\Loader\LazyChoiceLoader, which imply to use Symfony Form 7.2.
Since this version is compatible with Symfony packages 6.4 (https://github.com/symfony/form/blob/7.2/composer.json), we could bump requirements (and add an explicit dependency on symfony/form, since the feature is not optional AFAIK?)
