[openstreetmap/openstreetmap-website] Update Docker documentation and Dockerfile (PR #4101)

[Andy Allan]

@gravitystorm requested changes on this pull request.

A few things need addressing here:

* If compose v2 comes bundled with docker, then the installation instructions at the top of DOCKER.md need to be updated too.
* We want to keep the manual instructions and the CI docker tests in sync. So that means `.github/workflows/docker.yml` needs the same change from `docker-compose` to `docker compose`
* It might be worth removing the unrelated `ca-certificates` change from this PR, and resolve that separately.
