Refactored Docker workflow

Significant changes have been made to the Docker build and push workflow. The process now triggers on push events to the main branch, instead of manually via workflow dispatch. Removed steps related to Go setup, dependencies installation, and artifact upload. Introduced QEMU setup, Docker Buildx setup, Docker layers caching, and login actions for both DockerHub and ghcr.io. Also added conditional build and push actions for ghcr.io based on a new environment variable USE_GHCR.
