No way to add user meta data with the `Auth` component

Bug report

Describe the bug

There currently is no way of adding user meta data when using the Auth component similar to how you can via the client.auth.signUp function with code like:

supabase.auth.signUp({
        email,
        password,
        options: {
          data: {
            first_name: 'Will',
            age: 10
          }
        }
      })

Expected behavior

The ability to add meta data similar to the above example but using the Auth component.
