php8.2

This has been discussed in the past but the solution is usually to ask plugin authors ton update their plugins for improved PHP8.1/PHP8.2 compatibility, whereas I think this is clearly a problem inside Xenforo 2.2 codebase, up and including 2.2.15 The file ./src/vendor/dokuwiki/utf8/utf8.php...

PHP 8.2 will deprecate dynamic properties. For the most part, this doesn't impact XenForo, but XF\Payment\CallbackState still relies on dynamic properties on lines 113 and 134 despite also implementing __get and __set.
