Link to contributors in some other/better way

[peterbe]

Please be aware of this discussion: https://github.com/mozilla/kuma/issues/5717 I think stumptown-renderer would equally benefit from not having to render that massive list of names and URLs.

This issue belongs both and either here and in stumptown-renderer but they're intertwined.

Content in stumptown will almost certainly "always" (at least of URIs that existed on the Wiki) be a mix of historical contributions from the Wiki as well as git commits within a directory.

We will have to port the contributions from the Wiki into stumptown-content. Like we've already done We can union this by doing some fancy git log commands [0] as time progresses the list of contributions will be a little bit of Wiki historical and a little bit git log.

One big question; if we take head from https://github.com/mozilla/kuma/issues/5717 , especially in point-of-view of stumptown-renderer, if you don't display the full list of names, where else do you display it?

git log -M --follow --pretty=tformat:"%aN %aE" -- content/html/reference/elements/video/docs.md | uniq
