Recognise addons may become obsolete and require update after major FreeCAD update

**Is your feature request related to a problem? Please describe.**
After FreeCAD updates to a major (minor version), some addons may not function correctly or require an update themselves.

**Describe the solution you'd like**
it would be good if the Addon Manager recognised that the Github default workbench has changed and at least advised the user they need to

1. Delete the workbench
2. Restart FreeCAD
3. Reinstall the workbench with the Addon Manager ( To pickup the new default )
