Pre-pull Docker Compose Selectively Service Images Action

🚀 Overview

When running docker compose --dry-run, image pulls are only simulated which can cause the dry-run to fail since no actual images are pulled. This action pre-pull images for services in Docker Compose selectively in parallel rather than pulling images for every single defined service in a Compose file.
