fix: canonical links (#1262)
Browse files Browse the repository at this point in the history
Upstream Sphinx doesn't construct canonical links correctly for the
DirectoryHTMLBuilder.
When I introduced #650, it included a bug for `index.html` pages.

This PR adds a proper fix with tests this time to make sure that
canonical links are what they should be. This PR is a follow up of #1258
and reverts the change in `layout.html`. Checking the canonical link
shouldn't be done in the template.

It's reported here:
[#9730](sphinx-doc/sphinx#9730)
