Based off the help page, I would try adding  to the tag since that's the namespace it is located in, but I tested it and haven't received the desired results. You can try it to see if maybe I screwed it up in my testing, but don't expect results. From your testing and mine, it appears that the only way to do this might be JS.

You could try writing a JS script located at Mediawiki:Common.js using the .search method to read through the feed and if a href attribute contains  it will hide the revision.
