Perhaps we should just do fmt.Println(version) - allows for programmatic use too?

As far as I can tell, it is pretty standard for a tool to print not only its version but also its name. I quickly tried with docker, kubectl, terraform and some other tools and all of them provide the name as well. The same holds true also for the go command it self. Therefore I am in favor of keeping the name in there.
That being said, if you insist on having only the version printed, I will update the PR of course.
