useFileDialog: enable uploading a directory instead of files

[JakobMiksch]

Clear and concise description of the problem

I would like to be able to select a whole directory and not only single/multiple files when using useFileDialog

Suggested solution

useFileDialog could add the HTML attribute webkitdirectory to its settings which enables the capability to upload a directory.

See docs in MDN for details.
