Currently we only expand the teamsAppDefinition relationship in the query to retrieve the list of apps installed for a given user. We should include the teamsApp relationship to the existing $expand query parameter and add that to the output.

This returns information about the app distribution method used, which enables us to distinguish between apps that are installed from the store, organization catalog or sideloaded.

In the case of sideloaded apps, this helps developers identify apps that have been installed for development purposes.
