Add "Vote|null $vote" argument on method "PostVoter::voteOnAttribute()".

Fixes:
- The "App\Security\PostVoter::voteOnAttribute()" method will require a new "Vote|null $vote" argument in the next major version of its parent class "Symfony\Component\Security\Core\Authorization\Voter\Voter", not defining it is deprecated.
