MDL-87761 course: Add warning for phasing out subsection descriptions
The Description field within the Subsection edit form has been deprecated since Moodle 5.2 onwards (see MDL-87279).
To ensure a smooth transition and avoid data loss for our users, the XD team have prepared a solution to notify them
of this upcoming change in stable versions.
