Document the Edition Process with Codespaces

[boisgera]

(Use the README)

• [X] How to start/pause/stop the codespace
• [X] ~Document the npm run build and python -m http.server (or npx serve) process~
• [x] Experiment again with Vite HMR? Done! Works with some simple tweaks.
• [X] ~Can we serve the web site from root and never have to go into dist? Would be simpler~
• [x] ~How to git pull / commit / push (lifecycle)~
