Add a community Wiki section

[moul]

@jaekwon proposed creating a community wiki in the awesome-gno repository during one of the developer calls. This repository is the most official place for community-curated content.

What do you think about creating a simple wiki folder in the repo, allowing people to open PRs, review them, and eventually establishing stricter rules such as a fixed structure?

I think awesome-gno lacks visibility but maybe it would giving it some.

I can see an alternative though, it would be to:

1. encourage people to edit files in gnoland/website/pages (after some structuration, could be just creating a contrib folder or something like that for all I know),
2. having https://test3.gno.land/contrib be routed to https://staging.gnoland.land/contrib, so that it's updated daily.

This way, github users can easily see what's new in website/pages/contrib when git pull, and visit from their local gnoweb etc. So a markdown wiki, without the interactivity but having pretty much the same spirit.

(I guess those ideas are pretty similar all-in-all, since awesome-gno is linked from gno.land)
