Symfony deprecation warning.

[OleeOlsen]

Hi!
I get this warning with Symfony 7.3:
The "Symfony\Component\HttpKernel\DependencyInjection\Extension" class is considered internal since Symfony 7.1, to be deprecated in 8.1; use Symfony\Component\DependencyInjection\Extension\Extension instead. It may change without further notice. You should not use it from "A2lix\AutoFormBundle\DependencyInjection\A2lixAutoFormExtension".
