is ``@supabase/supabase-auth-helpers`` the recommended way to use supabase with next.js? just curious, because it's a community maintained package instead of official, but the official next.js examples use that package now (https://github.com/supabase/supabase/blob/88e2fc4485d458569a46e3a871e0350ff9fcdac6/examples/nextjs-with-supabase-auth/package.json#L10)
