Add Docker services for Rails 5.1, 5.2, and 6.0

Add Docker Compose services for older Rails versions to enable comprehensive testing across the full compatibility matrix: Services added: - rails-5.1: Rails 5.1.7 - rails-5.2: Rails 5.2.8.1 - rails-6.0: Rails 6.0.6 Usage: docker-compose run rails-5.1 docker-compose run rails-5.2 docker-compose run rails-6.0 This completes the Docker setup for all Rails versions supported in the CI matrix (5.1.7 through 8.1.2).
