fix: Update to Docker Compose v2 syntax

Docker Compose v1 is deprecated and has been removed from Github Actions
Runner images:
https://github.blog/changelog/2024-04-10-github-hosted-runner-images-deprecation-notice-docker-compose-v1/
https://docs.docker.com/compose/migrate/

Note that I've only changed the invocations used in Github Actions
because that's what I need to run in order to build a new image. It
looks like we also use docker-compose locally. Probably that version
will need updating and the various invocations fixing, but I don't have
time for this right now.
