[SecurityCsrf] Example is incorrect.

[void-azure]

On the form component documentation it says to use this example for csrf protection under version 6

use Symfony\Component\Form\Extension\Csrf\CsrfExtension;
use Symfony\Component\Form\Forms;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Security\Csrf\CsrfTokenManager;
use Symfony\Component\Security\Csrf\TokenGenerator\UriSafeTokenGenerator;
use Symfony\Component\Security\Csrf\TokenStorage\SessionTokenStorage;

// creates a Session object from the HttpFoundation component
$session = new Session();

$csrfGenerator = new UriSafeTokenGenerator();
$csrfStorage = new SessionTokenStorage($session);
$csrfManager = new CsrfTokenManager($csrfGenerator, $csrfStorage);

$formFactory = Forms::createFormFactoryBuilder()
    // ...
    ->addExtension(new CsrfExtension($csrfManager))
    ->getFormFactory();

But in symfony 6, $csrfStorage = new SessionTokenStorage() expects RequestStack.
