CLIP OS toolkit: Bump Python package dependencies

This Python packages bump is required in order to upgrade Pip to
version 19.1.1 which fixes a bug causing "pyproject.toml" file to be
considered eventhough "--no-use-pep517" is specified on the command
line (see pypa/pip#6434 ).
This bug was causing our CI systems to fail on the install of package
sphinx-autodoc-typehints which makes use of "pyproject.toml" file.
