update Authorizable contract parameter names (#33866)

There's a parameter mismatch found by Psalm in my new Laravel project. Base User class is using trait `Illuminate\Contracts\Auth\Access\Gate\Authorizable` with method `can` with signature `iterable|string $abilities`; interface is defined as `string $ability`. Different parameter naming could be a problem for named parameters in PHP 8.0. Inconsistent type hints could be a problem for mocking/extending/testing/whatever.

Error from Psalm:
```
ERROR: ParamNameMismatch - app/User.php:10:7 - Argument 1 of Illuminate\Foundation\Auth\Access\Authorizable::can has wrong name $abilities, expecting $ability as defined by Illuminate\Contracts\Auth\Access\Authorizable::can (see https://psalm.dev/230)
```
