Update API endpoint used for Archived projects

What does this MR do and why?

Related to #371923 (closed)

There is a bug on the Archived projects tab in the group overview where all groups, subgroups and projects are shown regardless of the archived status. This MR updates the API used to fix the bug. For the Archived projects tab we will now use the GET /groups/:id/projects API with the archived parameter. For context on why we decided to switch APIs see #371923 (comment 1090509501)
