So the only place I can find the last version of Drone is https://github.com/harness/gitness/tree/v2.20.0

You don't see how that's a bit ridiculous?

https://github.com/drone/drone redirects to harness/gitness too, leaving the entire https://github.com/drone organization without its major repo. Not to mention, again, that all GitHub links on https://www.drone.io/ are now 404.
