Cannot import npm specifier modules due to firewall

[justinmchase]

Describe the bug I cannot configure NPM_CONFIG_REGISTRY in the vscode extension.

https://deno.com/blog/v1.29#custom-registry-support-via-environment-variable

To Reproduce

1. Connect to a corporate VPN which blocks npm
2. Setup an Artifactory proxy
3. Attempt to import something with an npm specifier

import * as express from "npm:express";

Expected behavior

I expect to be able to have this succeed by importing through the proxy.

I would imagine it could be as simple as adding an option npmRegistry to the settings which would set that env variable before invoking deno.

{
  "deno.npmRegistry": "<url>"
}
