Refactor docker-compose installation in GitHub Workflow

Docker-compose installation has been moved in the GitHub Workflow (docker.yml) from the "test" to the "build" phase. This change ensures docker-compose is installed early on, making it available throughout the entire process. The steps include updating the package list, installing docker-compose, and confirming its installation.
