Moodle version: 4.3dev (Build: 20230602)

Discovered when creating a new JazzQuiz session. Receives the following error message:

The question/qengine.js has been deprecated. Please use core_question/question_engine

Does not affect Moodle 4.1. The qengine.js file says that it has been deprecated since 4.0. Should not be that difficult to resolve, but the replacement file core_question/question_engine does not seem to exist in the moodle directory. This was checked for moodle 4.1 and 4.3.

Resolved this by making the jazzquiz renderer check the current Moodle version and use the new question engine if the Moodle version is newer than 401 and the old one otherwise. This way, the jazzquiz plugin works fine with both Moodle 401 and 403. This was confirmed by tests on both these versions.
