Proof: manage webp uploads

[raphodn]

Story

We use mimetypes.guess_extension() to define the extension of the uploaded file

But image/webp doesn't seem to be managed by the server (nor my local environment - Ubuntu 22.04)

A solution seems to be to edit the server's /etc/mime.types : https://stackoverflow.com/a/67938698/4293684

But is this the best solution ?

Best is to manage it in the code (for future servers or users without this config)
