multi arch, safe ignore not exist arch

Hi, I use this docker registry UI and I have an issue...

Bug description

We have a custom mirror service for k8s fetch proxy, when attempting to fetch manifests for one architectures (e.g., ARM64), in service, other arch will fetch only as need, this is expected and safe.

but when use ui, if first arch return 404, the page will not load other arch

Expected behavior

Could we safely ignore these "404 Not Found" errors for not found architectures and simply gray out/disable the corresponding UI options instead of showing errors? This would improve user experience while maintaining clarity about available architectures.
