Update CacheInterface.stubphp

[michnovka]

The param signature has been changed and hence getting this error:

ERROR: ArgumentTypeCoercion
Argument 2 of Symfony\Contracts\Cache\CacheInterface::get expects Symfony\Contracts\Cache\CallbackInterface|callable(Psr\Cache\CacheItemInterface, bool):float, but parent type impure-Closure(Symfony\Contracts\Cache\ItemInterface):float provided (see https://psalm.dev/193)

This fixes it.

Not sure what to do with the failing tests, they dont seem related to my code
