Cannot access resources of ArchWiki extensions
https://wiki.archlinux.org/extensions/WikiEditor/modules/images/toolbar/example-image.png which is seen in the WikiEditor toolbar in Help > Files returns 404.
This is presumably because roles/archwiki/templates/nginx.d.conf.j2 doesn't allow that path.
The https://www.mediawiki.org/wiki/Manual:Short_URL/Nginx example uses different regexes. It might be a good idea to update nginx.d.conf.j2
to match that example.
