As described in Merge request 222, the previous solution is not the best possible solution and was also missing documentation. Adjust the suggestion to the current GStreamer mono-repository. And apply this change after reverting the previous commit. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1743>
