hack/make.ps1: remove the .0 suffix from go version

We would like to use a version with .0 suffix (like 1.11.0) in
Dockerfile, so that once a .1 version is out (like 1.11.1) we
won't accidentally switch to it.

Unfortunately it's not possible to use .0 suffix currently
as it breaks the check in make.ps1. This patch fixes that.
