Can't upload images

[danieladugyan]

Description

I tried to publish an article with an image, but it didn't work even though I tried multiple times.
original source: in-person bug report

Steps to reproduce

Step 1. Go to https://www.dsek.se/news/create.
Step 2. Add an image.
Step 3. Try to publish the article.

Further information

It works sometimes so I'm guessing this has something to do with the image, probably its size. If that's the case, make sure the error message reflects that clearly.

Follow this guide to implement file uploads directly from the client. Return the pre-signed URL to the client and call fetch from the client instead of from +page.server.ts.

@trilleplay Feel free to fix this if you want to, otherwise we'll get to it next Tuesday.
