Closes #1506

@dicej @tschneidereit I had an assumption that we would be able to redirect requests from go.bytecodealliance.org to github.com/bytecodealliance/wit-bindgen/crates/go/src/package. Is this actually possible, or will we need to discuss other paths forward?

Will the git retrieval work from a nested directory like this?

[tschneidereit]

@asteurer I unfortunately don't know how this works, apologies. One important thing I want to emphasize again is that it's crucial to ensure that existing code using go-modules continues working, so whatever the setup looks like in the end, it needs to ensure that current links continue to work as well.

Good to know! I'll convert this to a draft PR until I've found a way to properly test everything.
