Figure out how to release to gopkg.in

I think we do not need to do anything special to release to gopkg.in. Taking a look at this page. There are two URL patterns supported:

gopkg.in/pkg.v3      → github.com/go-pkg/pkg (branch/tag v3, v3.N, or v3.N.M)
gopkg.in/user/pkg.v3 → github.com/user/pkg   (branch/tag v3, v3.N, or v3.N.M)

This is something we already follow this. Therefore, the following should work out well:

gopkg.in/urfave/cli.v1 -> v1 branch or v1.x.x release tags
gopkg.in/urfave/cli.v2 -> v2 branch or v2.x.x release tags

This would work very well for those not using Go Modules. I have also managed to reproduced this :

Code Setup

Output for v1

Output for v2

I had disabled Go Modules for above project and instead used the project folder as the GOPATH

Got it, so it sounds like people who want to download the package from gopkg.in are currently 100% capable of doing so 👍 So I'll close this ♻️
