Symfony version(s) affected: 4..

Description
I have issue with latest update for symfony/security-bundle and symfony/config. Error message is:

ReflectionException: Class Symfony\Component\Templating\Helper\Helper
not found in /usr/share/nginx/html/vendor/symfony/security-
bundle/Templating/Helper/LogoutUrlHelper.php:23

This works well before last update and i see there was issue last year similar to this with explanation that templating is required, but i thath package is not in composer.json required packages of security-bundle.

How to reproduce
Update security-bundle to latest 4.2.3 version

Possible Solution
