Update installation procedure for Go 1.17

[Muamaidbengt]

Since Go 1.17, go get is deprecated for installing executables and one should instead use go install (with a version suffix) for such use cases.

As far as I can tell, there's no separate invocation required to update an executable installed in this manner. 🤷‍♂️

I was about to open this RP myself, looks good to me :)
