Enhance online quizzes with Moodle 4.0 question bank improvements

In Moodle 4.0, the question bank makes it easier for teachers and course creators to manage and collaborate on quiz questions. In the question bank, teachers can now decide whether a new question is published and ready to use or kept as a draft. Teachers can view and add comments to questions, view a history of changes and versions of a question, and preview each of them.
