## Description

I'm seeing warnings when I run 'jlpm'

```console

➤ YN0002: │ @jupyter/builder@npm:1.0.2 doesn't provide webpack (peeeb5), requested by source-map-loader
➤ YN0002: │ @jupyter/builder@npm:1.0.2 doesn't provide webpack (pa2424), requested by style-loader
➤ YN0002: │ @jupyter/builder@npm:1.0.2 doesn't provide webpack (p5c888), requested by worker-loader

```

['worker-loader'](https://www.npmjs.com/package/worker-loader) appears to be unused by jupyter-builder.
