Make it possible to return values from action callbacks

[MrOxMasTer]

The point is that since useStateAction doesn't support progressive enhancement and it doesn't work without javascript, there is no way to return a value other than the one given by the validation library when a validation error occurs.

It can be done with useStateAction:

Action:

export const checkUpUserAction = actionClient
  .schema(formDataCheckUpUserSchema)
  .stateAction(
    async ({ parsedInput: { email } }) => {
       ...
       return user;
    },
  );

client:

const 
const [error, setError] = useState(...); 
const { execute, isPending, input } = useStateAction(checkUpUserAction);

input ...

How to do it useActionState:
???
Action:

export const checkUpUserAction = actionClient
  .schema(formDataCheckUpUserSchema, {
     handleValidationError: ... // No
  })
  .stateAction(
    async ({ parsedInput: { email } }) => {
      ...
      return user;
    },
    {
      onError: ({ clientInput }) => {
        console.log('ON_ERROR');

         return clientInput // No
      },
    },
  );
