Restructuring the Community Page

The [Community page](https://graphql.org/community/) has similar issues to the Code page (#911) - there are no guidelines for what should be featured there.

However, with the Community page, I believe there are other considerations. This page was created when GraphQL was newly announced and the exposure was limited. Now there are more books, videos, learning resources, etc. than can be represented on this page.

A community page might still make sense, but we should think about what sections should be included and what the criteria are for the resources featured. This likely wouldn't happen until after the Gatsby migration (#875) is complete, but we can start thinking about it already.

Curious to hear anyone else's thoughts on this!

Commencez par examiner la Community page existante et l’issue associée de Code page (#911), puis prenez en compte la Gatsby migration référencée dans #875. L’issue ne nomme ni fichiers ni tests ; le travail ne sera terminé qu’une fois la structure de la page et des critères clairs pour les ressources communautaires mises en avant convenus.
