Page contributor list

[dtinth]

Right now each page metadata shows just the last updater. Ideally, we want to show the contributor list, because the wiki is maintained by many people.

• Since our wiki content is already backed by GitHub and the content is public, we can directly query GitHub for a contributor list.
• I think it’s better to do it on the website repo rather than on contentsgarten repo, to keep contentsgarten’s scope limited. If it is needed for other sites, we can port the code later.
  • From research, to make a GraphQL API call (used for querying co-authors) the request needs to be authenticated. To authenticate without an active user, the authentication needs to be as a GitHub App Installation. But our website is an OAuth App, so a new endpoint has to be implemented.
