'course_group' in form shadows 'course_group' in path, which hides it in documentation

[alexdlaird]

When updating a Course, you may pass a "course_group" parameter in the body to move the course from one CourseGroup to another. Since this field shadows the course_group in the path (which maps to the current CourseGroup, whereas the one in the body maps to the CourseGroup to be moved to), the generated documentation removes the "course_group" field from the body.

This is also true when updating a Material.

As this functionality is not currently supported by the frontend anyway, this is a low priority, especially given the functionality itself also works. But documentation should be updated to reflect.

Closing, as the Helium project is not currently active.
