fix: PHPStan detecting type correctly after usage of Assert::assertIsList

[mitelg]

Hey there,

recently I found that the assertIsList method does not tell PHPStan correctly that the variable is of type list afterwards. This PR is fixing that.

I wanted to add this to 10.5 branch first, but I saw, that there are no phpstan-assert annotations at all, so I was not sure, if that was reasonable.

This is my first contribution here, so I hope, I did everything correct. Not sure, if I need a test for this

See phpstan/phpstan-phpunit#212 for reference

just realized we need the same phpdoc on src/Framework/Assert/Functions.php, right?

Cherry-picked into 11.4 and merged to 11.5 and main from there.
