Currently every time we run the deploy fastlane lane (which is kicked off from the Deploy Jenkins job), both the Wikipedia app and the Wikipedia Staging app is built and deployed. We don't need to test the Wikipedia Staging app that often, so we need to remove it from our basic deploy lane and instead create a dedicated deploy staging lane and Jenkins job to explicitly deploy Wikipedia Staging separately on an as-needed basis.

As a part of this - delete the Wikipedia.xcworkspace and confirm CI still works.
