Then it can set up the dev server websockets

This adds a line to the devcontainer global bashrc that checks if the Github
Codespaces variables are set, and if so sets Webpack to use the Codespaces prot
forward for its live reload websocket.

We should maybe use a Dockerfile-based build to drop this line in the global
bashrc instead.

Create React App doesn't provide a WDS_ env var to control

So we have to actually put the server into HTTPS mode if we want WSS
used for the hot reload server. Luckily, Github's proxy ignores
