The ReplaceSafeFunctionsDynamicReturnTypeExtension is partial and was only handling preg_replace's return type. I've added both preg_replace_callback and preg_replace_callback_array.

This PR fixes tests with phpstan > 2.1.11 as well by using assertSuperType instead of assertType in order to deal with lists.
