qtwebchannel maintainer doesn't have permissions to override sanity bot and unwip a change

  <arehn[m]> this is funny. I've got approvers rights on QtWebChannel, but I can neither +2 a cherry-pick to 5.15 nor override the sanity check. Not that I'd want to, it just occured to me when I hit the "Reply" button. The relevant change is here: https://codereview.qt-project.org/c/qt/qtwebchannel/+/310395
[11:08:12]  <arehn[m]> Could someone shed some light on this?
