Refactor HTML Empty Line Removal Step in github-actions-s3-publish.yml

- REMOVED: The previous shell command using sed to delete empty lines from HTML files.
- ADDED: A Python script that reads each HTML file, filters out empty lines, and writes the cleaned content back, enhancing cross-platform compatibility and maintainability.
