WISH: webextension / webworker

[ejfasting]

Hi,

It would be neat if the sample also had the option to run on the webworker, as a webextension.
This, possibly, would mean to include this (or similar logic?): https://github.com/volarjs/vscode-typescript-web

This could also, ofc, be a wish for a separate repo, starter-webworker, to not clutter this one :)
