Exploration: Support HTML export for Web extension (vscode.dev/github.dev) powered by WebContainer API/Sandpack 2.0

[yhatt]

WebContainer API provides Node.js tool chain support working completely on Web, without any cloud servers.

And Sandpack 2.0 able to run Node.js with the browser too.

Marp CLI, an internally running process of the export command, is also working on WebContainer well, so either of them probably can get back a missing feature of the web extension, the export command.

FYI: Both are still not able to work export to PDF and other file formats.

I think it's better to make swappable the proxy for fs file system API through Marp CLI API.
