Add attempts method to rate limiter

[nicolaferrara82]

At the moment it was missing attempts() method for the $limiter and I am unable to track it in my custom login procedure:

Fortify::authenticateUsing(function (Request $request) {
            $user = User::where(config('fortify.username'), $request->{config('fortify.username')})->first();

            if($user){
                if(!$user->active){ 
                    $limiter = resolve(LoginRateLimiter::class);
                    $limiter->increment($request);

                    throw ValidationException::withMessages([
                        'inactive' => [trans('auth.inactive',['attempts' => $limiter->attempts($request)])],
                    ]);
                }

                if (Hash::check($request->password, $user->password)) {
                    return $user;
                }
            }
});
