chore: update Docker publish workflow for improved compatibility

- Changed the runner from 'warp-ubuntu-latest-x64-4x' to 'ubuntu-latest' for better support.
- Added setup for Docker buildx as a workaround for a known issue.
- Updated the Docker build and push action to use 'docker/build-push-action@v6' for enhanced functionality.
