Documentation viewer

[firelizzard18]

I think it would be possible to implement a godoc viewer inside of VSCode without a long running process. godoc -url <path> will output the HTML that godoc generates for that path. If I can hook into the VSCode webview to intercept requests, I think I could make this totally functional.

@hyangah WDYT? Is this worth pursuing?

This would be useful for looking at documentation of the project you're currently working on. Often I want to see the godocs for whatever I'm working on, before I push it. This would also help users working on private and/or not open source projects.
