ci: Update to Docker Compose V2 syntax

This commit refactors the `ci.yml` workflow to use the modern Docker Compose V2 syntax (`docker compose` instead of `docker-compose`).

The manual installation step for the Docker Compose plugin has been removed, as the GitHub Actions runner environment includes a compatible version of Docker Compose V2 by default. This simplifies the workflow and relies on the standard tooling provided by the runner.
