In this PR I'm removing the ionic3 code (the ionic5 app was released on 2021 so it should be safe to remove it).
I also removed the usage of core-course-module-description component for newer app versions, it is deprecated and will be removed in a future version of the app. It should have been removed already, but we kept it in the app because some plugins still use it.
