        Install Docker on the runner environment
        This action uses Docker's official convenience installation script at https://get.docker.com/

        By default, Docker Buildx is also configured to provide support for modern Docker build workflows, including multi-platform image builds, advanced caching, and BuildKit features.
        Existing Docker installations are detected automatically and will not be reinstalled.
