Add publish-vsce job

- Add publish-vsce job to publish the extension to the Visual Studio Code Extension Marketplace.
- Remove the `@remarkjs` scope since VSCE doesn't like it.
- Use manual `npm config` instead of `actions/setup-node@v2` since the latter only seems to work with scoped packages (see actions/setup-node#73).
