Several Node.js services based on service-template-node include a static/index.html file with old HTML, which keeps showing up when doing skin or JS related migrations/deprecations. These likely don't render well currently and also may no longer match current MW output behavior. These are usually not served to clients behind RESTBase and serve no purpose besides demonstrating how to serve a static file.
This task is to either simplify the HTML or remove the file.
If we remove the file we should consider to also disable serving of static files in app.js.
