There is no reason to filter out these warnings only in tox builds
as the issue comes from upstream httpdomain not in sync with latest
sphinx API.

It also enables to unstuck swh-web and swh-docs builds on Jenkins.

Since the release of sphinx 4.1, a new warning related to httpdomain
extension appeared when buidling swh-web documentation.

It is not critical and is due to httpdomain not in sync with latest
changes in sphinx, so filter out that warning as it makes sphinx
builds fail for swh-web on Jenkins.

The following document demonstrates how to create a new swh package in the current swh

build the new module.

The FAQ was put in a single file in faq/faq.rst as a hack, using
multiple top-level headers in the same file to make them appear
in the global TOC.

With this change, the TOC is moved to the index.rst file, with
a single top-level header, and uses a local TOC instead, as it
should be.

Additionally, this removed the manually-written TOC in the main
index to use an auto-generated one.
