Fixes #4192
Changes proposed
The syntax in /core/lib/Drupal/Core/Template/TwigExtension.php has changed and the new filters are now declared with "new TwigFilter" instead of "new \Twig_SimpleFilter". Same thing for TwigFunction.
We need to update the file /src/Robo/Commands/Validate/TwigCommand.php to reflect those changes.
Steps to replicate the issue
Previous (bad) behavior, before applying PR
The TwigCommand.php is searching for "new \Twig_SimpleFilter" in Drupal core to add exception but these filters don't exist anymore.
Expected behavior, after applying PR and re-running test steps
Run the command blt validate:twig and it should contain valid syntax.
