Rhino3d.com/download still shows WIP

Minor web update for the download page needed to show that Rhino 9 is in beta :slight_smile: :

@martinsiegrist I see you struggled to find a relevant topic for this too :grinning_face_with_smiling_eyes::+1:

But that just means we can still implement more ideas! Quickly before they change it! :joy:

Haha yes, I just corrected a typo in your topic title…

Actually why not just move it into Serengeti?
