Summary: This diff adds the cocoapod's github repo as a source otherwise Cocoapod uses the cdn to refer the latest pods. We need this as in create_pr job we update the Podfile.lock of this RN sample project and it fails to find the latest flipper pod because Cocapod takes a while to update its cdn. Reffering the specs directly from github repo solves the issue. ## Changelog Add github spec repo as a source in the Podfile.
