Subject: [PATCH] build: add script to patch API URL for runtime

The application currently loads the API URL by trying a PageConfig
option and then falling back to a localhost hardcoded URL. This
yarn script uses `jq` to inject the environment variable API_URL
into the built app's config at `dist/jupyter-lite.json`.

Additionally, a yarn script `build:all:prod` tacks this script on
at the end so that you can run API_URL=... jlpm build:all:prod
