SUMMARY Desktop files (*.desktop) have three properties: Name, Description (GenericName) and Comment. If the Name and Description are the same, a description won't be shown when the user hovers over the app's icon in the task manager. Help Center's desktop file has the same name and description. So the desktop file description could be changed to something like "Documentation viewer".
Since this is a Plasma-only application with a generic name (not a "brand" name), it doesn't really need a description. The same was decided for Welcome Center in BUG 504401. So instead of changing the description, it should just be removed.
This issue is the exact same as BUG 504398, which was marked as RESOLVED INTENTIONAL. I'll do the same here.
