Subject: [PATCH] Relocate Docker build and push process to GitHub Workflow

The Docker image creation and pushing procedures have been moved from the goreleaser.yaml file to a separate GitHub Workflow file docker.yml. This shift gives a more granular control over the Docker image build and push operations with specific GitHub Actions. Also, added the Dockerfile instructions and docker-files for image building to cope up with the changed Docker process.
