Limit add-on settings menu list to bundles (#2217)

When installing rule templates or UI components or blockly libraries
from the marketplace, they get an entry in the add-on settings menu.
There is nothing that can be configured in these types of add-ons.
Therefore limit the list to bundles and features.
