[PHP 8.4] Fix implicitly nullable type declarations

Created on 11 April 2025, 28 days ago

Problem/Motivation

In PHP 8.4, declaring functions/methods with parameters containing null as a default value, but without null as one of the types (either as a nullable syntax or as a Union type with null) is deprecated.
