PHP 8/php-generator v4 compatibility update (#5)

* PHP 8/php-generator v4 compatibility update

PhpGenerator\ClassType.php was refactored in v.4, so $methods-property became private. Fixed by using $class->getMethod('initialize') instead.

* Update HttpAuthExtension.php

tabs instead of spaces

src/HttpAuthExtension/HttpAuthExtension.php
