Symfony version(s) affected

Description

why its type-hinted as string and then there is this?

https://github.com/symfony/symfony/blob/6.3/src/Symfony/Component/Security/Core/Authorization/Voter/Voter.php#L38-L40

Related issue:
#37325

This messes up the Static analysers.

How to reproduce

Symfony 5.* https://phpstan.org/r/9786dc67-c9ee-4bf7-9232-ffbc4c082256
Symfony 6.* https://phpstan.org/r/c28b5633-bf91-43da-ab34-c0bca8c42711

Possible Solution

either make it mixed either remove the hack + typehint isGranted with string also. This hack exists since 5.0 - it should be removed in 6.0 as BC can be break in major releases.
