Add support for multiple segments in namespace and package

[peter-facko]

I tried using this extension (version 0.3.18), and with lines like

package com:organization:category/topic/package;

I am getting an error

expected '{', found ':'wit-syntax(wit-parse-error)

That syntax isn't currently valid for WIT itself, though there's a PR open for changing that.

I'll close this, since the extension is working as expected for the time being. I'd recommend subscribing to the PR for the WIT change if you're interested in tracking progress on this.

I was using this https://github.com/WebAssembly/component-model/blob/main/design/mvp/WIT.md#package-names and this https://github.com/WebAssembly/component-model/blob/main/design/mvp/WIT.md#package-declaration as a reference, and it describes it, so I thought that it is valid WIT.

Ah yeah, that is a bit confusing I agree: the Component Model proposal uses the 🪺 emoji to indicate future features that aren't yet stable, so the fact that the "nested namespaces and packages" paragraph starts with that emoji means it's not yet usable. The package-decl production should probably contain a current version without nesting and an emoji-gated one with nesting, so that seems like a bug in the spec.
