Store page should get some love

The store page (https://apps.nextcloud.com/apps/preferred_providers) should get some love. It is missing basically every information and link.

Hey! :)
This app is for dedicated providers only, to be fair it's only on the store so that they can have automated updates.

I'm not sure we need to have more visibility on this :)

Maybe someone else finds this interesting for their cloud setup while searching trough the store but does not find any information on it. I don't think it hurts adding at least a link to this github repo.
