Dataset upload UI suggests uploading multiple files is possible

[PGijsbers]

A user tried to upload a multifile dataset and only got cryptic errors. The errors may or may not be related, but the text needs an update either way.

" I keep getting a 502 proxy error few seconds after I hit the upload button, while the uploading screen hangs forever."

@PGijsbers Hi! I’d be happy to work on this.

Just to confirm scope: would you prefer

1. updating the UI text to clearly state that only single-file uploads are supported, or
2. adjusting the upload UI so it no longer suggests multiple files can be uploaded?

Once confirmed, I can open a PR.

Hi @revaarathore11! Thanks for the offer! Right now there is a major rewrite of the frontend underway replacing virtually everything (rewrite from React+JS to NextJS+TS). I assume that this issue will no longer be relevant with the new frontend, but if it is, I'm sure we could use some help!

@joaquinvanschoren is the main owner of the repository, maybe he can give a timeline.
