Latest merge of "wip-phpstan-level6" in TT-RSS breaks plugin feediron

Expected Behavior

Plugin works with latest version of TT-RSS

Current Behavior

PHP Fatal error: Declaration of Feediron::csrf_ignore($method) must be compatible with IHandler::csrf_ignore(string $method): bool in /var/www/html/tt-rss/plugins.local/feediron/init.php on line 54

The updater throws the same error.
