Answer 1

Don't use SubmitButton as a type. The right type is SubmitType

use Symfony\Component\Form\Extension\Core\Type\SubmitType;
// ...
->add('Ajouter',SubmitType::class);

By the way, Symfony consider as a best practice to not put the submit button in the form class.

Best Practice

Add buttons in the templates, not in the form classes or the controllers.
