Pull Request Overview

This PR fixes the deprecated usage of Reflection*::setAccessible() method to maintain compatibility with PHP 8.5, where this method has been deprecated. The change ensures the code continues to work across different PHP versions by conditionally calling setAccessible() only for PHP versions below 8.1.

• Updates reflection property access to handle deprecated setAccessible() method
• Adds version check to conditionally call setAccessible() for older PHP versions

Generally speaking Copilot is right as since 8.1 the method is no-op but deprecation happened only in 8.5
