[Security] [Documentation][Voter] updated documentation for CacheableVoterInterface

[dylan-b-efficience-it]

I noticed that the Voter documentation, in particular the code illustrating the point "The Voter Interface", was not update. To explain further, in the Voter.php file on GitHub, we've also been implementing "CacheableVoterInterface" since Symfony 5.4.

So I'd like to suggest this change to the documentation.

Suggested change

	:class:`Symfony\\Component\\Security\\Core\\Authorization\\Voter\\VoterInterface`,
	:class:`Symfony\\Component\\Security\\Core\\Authorization\\Voter\\CacheableVoterInterface`
	:class:`Symfony\\Component\\Security\\Core\\Authorization\\Voter\\VoterInterface` or
	:class:`Symfony\\Component\\Security\\Core\\Authorization\\Voter\\CacheableVoterInterface`

I'm not sure about why Voter implements both interfaces explicitly but since CacheableVoterInterface extends VoterInterface perhaps the documentation can mention that only one is needed ?

@dylan-b-efficience-it thanks for this contribution, but we recently updated this page in a different way. We created a whole new section for cached voters and reordered some other contents. See #21040.

That's why we're closing this. We're sorry but we hope you understand it. Thanks!
