Plugin is Not PHP 8.2 compatible

Please declare $_modules_manager as public variable in loader.php as it is not allow to dynamically create a variable anymore in php 8.2. In php 9.0 it will be a fatal error.

Deprecated: Creation of dynamic property loader::$_module_manager is deprecated Line 556 in loader.php

    $this->_modules_manager = new Manager();

// PHP <= 8.1: Silently creates dynamic $user->nane property.
// PHP 8.2: Raises deprecation warning, still creates dynamic property.
// PHP 9.0: Throws Error exception.

Thank you
