Switch from docker-compose to docker compose. (#1393)

Docker apparently moved the standalone `docker-compose` command into a
subcommand of the `docker` command, and they deprecated the standalone
command. GitHub Actions recently updated to a new enough Docker version
that dropped the standalone `docker-compose` command, which is causing
CI to fail.

This updates both the CI configuration as well as our README to only use
the subcommand version.

 This will spin up a web server at http://localhost:1337/ and print out a URL to use. You should manually enter it into your browser to start the tests.
