export getPreviewsLoaderHook for public use

[CanRau]

Is your feature request related to a problem? Please describe.
I'm building an upload experience for our lexical editor and would love to directly use getPreviewsLoaderHook instead of <UploadPreview/> or having to unnecessarily rebuild the logic myself as everything is already there 😇

Describe the solution you'd like
Export getPreviewsLoaderHook to make it publicly available 🙏
Hope it's not considered an implementation detail 🤞🏼

Describe alternatives you've considered
Rebuilding the generation of preview myself

[CanRau]

Might still be nice, though I'm not just using a couple of lines to generate them myself and am good to go, forget sometimes that it's not that hard 😅
