✨ feat(GenerationContext.py): add support for z-index of moviepy clips to improve video rendering
The indentation issue in the process() method has been fixed. The z-index of moviepy clips has been added to improve the rendering of the video. This allows the clips to be rendered in different layers based on their index, resulting in a more visually appealing video.
