Update Docker commands in GitHub workflow

The Docker commands in the GitHub workflow file have been updated from "docker-compose" to "docker compose". This is reflected in the lines for checking code style, installing dependencies, and running the test suite. This change ensures compatibility with newer Docker versions where "docker compose" is the recommended syntax.
