issue: form action does not trigger client side validation

Steps to reproduce

Using Server Actions is now the official and recommended way we build forms in React (Next.js). Wrapping an action in onSubmit function is currently the workaround but does not look like a nice one.
The validations we put in register function should be triggered by <form action={formAction}>
Currently it is not the case.

Expected behaviour

When using React Server Actions with action attribute the client side validation is still triggered.
