feat(ci): add GitHub Actions workflow for Docker image build and push

This commit introduces a new GitHub Actions workflow to automate the building and pushing of Docker images. The workflow triggers on pushes and pull requests to the main branch, specifically when changes are made to the Dockerfile or the workflow file itself. It uses GitHub's Container Registry for storing images and supports multi-platform builds for amd64 and arm64 architectures.
