Remove token check from Authorization example

[joevallender]

Developers who are not using the API permissions addressed in the next section won't check tokenCan. It's just a tiny thing, but it's a little more intuitive for paste-and-change learners like myself.

Actually, Laravel\Jetstream\HasTeams.php appears to be performing the same checks as the API permissions example.

If so, that section is no longer needed, and one example would suffice. Perhaps just the code below, to continue with the server example.

/**
 * Determine whether the user can update a server.
 *
 * @param  \App\Models\User  $user
 * @param  \App\Models\Server  $server
 * @return bool
 */
public function update(User $user, Server $server)
{
    return $user->hasTeamPermission($server->team, 'server:update');
}

If I've understood this correctly, I will further update the pull request
