chore: update Docker image configuration and enhance CI/CD workflow

- Changed the Docker image reference in docker-compose.yml to use dynamic environment variables for better flexibility.
- Updated the GitHub Actions workflow to set the image tag based on the commit SHA, ensuring unique tagging for each build.
- Added environment variable definitions for Docker Hub credentials and image tag in the deployment process.
