Can't define "Super User" for each guard

[pintend]

Description

when using multiple guards you cant define a "super user" for each guard because the before callback doesnt know what the guard is.

The guard is removed from the arguments here https://github.com/spatie/laravel-permission/blob/c99dca701d60e1a2d1f839c9bfd102b8098432fe/src/PermissionRegistrar.php#L126C26-L126C37

This might be necessary when an application has different admin portals and a user can be a super admin in one portal and not the other.

This would be a breaking change...

Steps To Reproduce

1. create a Gate::before callback with 3 arguments, (Authorizable $user, string $ability, array $args = [])
2. call Gate::authorize($permission, $guard)

Callback $args will be an empty array
