Fix tox docs-html builds

These have been broken for about a month now because of the upgrade
to Sphinx 2. This upgrade happened automatically because we do not
have the version pinned.

Luckily this issue appears to only be from having Python 2 syntax in
the docs script, so making that compatible with Python 3 fixes the
error and allows the docs to pass.
