Subject: [PATCH v2 5/5] scripts: sphinx-pre-install: place a warning for Sphinx >= 3.0

Newer versions of Sphinx have a known bug:
	https://github.com/sphinx-doc/sphinx/pull/8313

Those currently produces 11 false-positive warnings On Sphinx
version 3.1+.

While Sphinx fix is not applied, let's warn adventurers that would
be using Sphinx installed via distro packages.
