Remove nonos-sdk-v2.2.0-28-g89920dc aka 3v0, since we have a real v3
Remove 3.0.0...3.0.4 to reduce overhead in maintaining a bunch or binary patches
Update our docs and menu opts to mention 'experimental' status
Old versions still remains in git history, so anyone wanting to play around with 3.0.x could still make use of that work
