Currently, we are serving a custom 404 page for those projects that have a
404.html
on their docs root path. This produces projects usinghtmldir
Sphinx Builder to not serve custom 404 pages because this file is called404/index.html
.This PR adds support for
htmldir
Sphinx Builder by trying first one file and if it does not exist try the other one.
