Generic build samples needed

We have two sample generic builds so far: [C](https://github.com/axodotdev/cargo-dist-c-example) and [JavaScript](https://github.com/axodotdev/axolotlsay-js). There's also a real-world [Objective C sample](https://github.com/mistydemeo/mt32-volume). We should consider what other languages we might want to demo too. Suggestions from the community welcome!

- [ ] Go

Start by reviewing the linked C, JavaScript, and Objective C sample repositories and the cargo-dist generic build workflow. Clarify which additional languages are wanted, then define and add the Go sample so it demonstrates the intended packaging path and completes the Go checklist item.
