Can you fix the failed CI test?

I've modified gno version so that the output is like the one you proposed in this issue #3005. The output is in this format [branch].[N]+[hash] or [tag] for when there is a specific tag pointing to the commit. Is this what you expect from the gno version command? @thehowl

A few notes:

• Instead of having this in cmd/gno, make a package gnovm/pkg/version, with var Version = "develop"
  • This will default to "develop" as a version, when somebody uses go install / go build directly.
  • It also allows us to eventually have this as gnoland version, too.
• The ldflag should also go in the goreleaser set up: .github/goreleaser.yml

Can you extend the existing GOBUILD_FLAGS?

These txtars test nothing :P
