New /community page

[raphodn]

Story

We recently added a page to showcase reuses (#842).

• but the url has a conflict with the server config (nginx ?), so its not easy to reach (nor shareable) : https://prices.openfoodfacts.org/reuses
• we could add more info

=> replace /reuses by /community ?

Ideas of things to add

• discussion places (Github, Slack, Forum)
• Link to the API
• Showcase of reuses (currently under /reuses)

Add a short blurb on that page to describe what process users need to follow to nominate a new category to be created for bulk/per weight/per item products without EAN ( fresh produces, vegetables, fruits, meat, bread, etc...)
