The issue summary says the "twig file needs to be refacored", but this patch only contains CSS changes and removing the todo from the twig file doc block.

@markconroy As https://www.drupal.org/node/3010558 is fixed.

So I have removed the todo comment from the twig file. And added the required CSS on form-item__error-message class. As suggested in parent issue.
