[fix] Improve sharp failure fallback about ghost HOT 1 CLOSED

I've found a temporary workaround, after going through some of Ghost's code. It seems like there is a check which prevents sharp from running at all, here.

So the solution was to:

1. Enter the docker container
2. cd ./current
3. Run yarn remove sharp, and then,
4. Run rm -rf node_modules/sharp
   To completely uninstall and clean sharp.

You would also need to add this to config.production.json:

{
   ...
   imageOptimisation: false
}

Doing the above completely disabled sharp and now allows me to upload images (albeit, the images are a bit large, but I can make do :D)

from ghost.
