Fix ImageSlider: use gradio_imageslider custom component

- ImageSlider is NOT built into Gradio, it's a separate package
- Added gradio_imageslider==0.0.18 to requirements
- Changed gr.ImageSlider to ImageSlider from gradio_imageslider
- Pinned gradio==4.44.0 (compatible with the component)
- Added huggingface_hub<0.24 to fix HfFolder import
