Why do you need this?

First of all thanks for k3sup! I can recommend it to everyone! I was looking for a way to upgrade K8s version but couldn't find it in the docs. I reran the bootstrapping commands and that did the trick so it seems to be (at least) possible. A couple of lines on how to upgrade K8s version in the docs would be very helpful.
