Support mediawiki-codesniffer@45.0.0, PHP 8.4 readiness #62
Description
This repository is currently using version 34 of the Mediawiki coding style phpcs rules. If the code aims to comply with Mediawiki style guidelines, it makes sense that it continues to comply at current versions of the rules.
Besides being simply different, the newer versions of the rules introduce, for example, MediaWiki.Usage.NullableType.ExplicitNullableTypes, which enforces compliance with coming deprecation rules in PHP 8.4 concerning nullable types. If the code does not remove the soon-to-be-deprecated form of nullable type declarations, the library will no longer be usable in Mediawiki for PHP 8.4 deployments.
