These were pinned in gradio-app/gradio#4885 to prevent gradio apps from breaking.
Relaxing the deps reintroduces this issue. I suppose that is better than keeping a broken build, but making the correct major versions available would arguably be the better solution.

Ok, then I would propose that this breakage doesn't block the arrow upgrapde.
