build: update Docker dev environment

[eatyourgreens]

• add some more local code directories to the docker dev build.
• update the docs.

I think I've got all the places that you might want to make changes while working on the app, but I could be wrong.

there are a few more (lib, scripts, config, docs, ...). Perhaps you could map the entire root dir to /app/?

[eatyourgreens]

I'm not sure about directories like docs, because they aren't used by the running Next.js app.

It might be worth adding a docs service to the compose file, though, so you could see the Next.js app on one port, and the docs site on another.

I'm also wondering whether to add a CLI shell so that people can run yarn scripts inside a container. At the moment, you can't easily run the tests in Docker.

Just tried running the tests in a container, and they failed with missing dependency errors. That's a problem for another day.

docker compose -f docker-compose.dev.yml run --rm gutenberg yarn e2e

lib would be an important directory to include

scripts folder too.

You also need files from the base directory, the next.config, the cypress.config and possibly the cypress.d?, tsconfig, tailwind config, the .env and .local.env.
