[11.x] Add symmetrical convenience method (laravel#50408)

* Add symmetrical convenience method

Since a `redirectGuestsTo` convenience method exists, I felt a `redirectUsersTo` convenience method should also exist. Especially since `users` is the second optional argument, as this would avoid using named parameters when it's the only redirect a user sets.

* Update Middleware.php
