As discussed (see Links), there is some inertia to move to the recent Sphinx versions for the doc build environment. As first step, drop the version constraints and the related comments. Then, the sphinx-pre-install script will fail though with: Can't get default sphinx version from ./Documentation/sphinx/requirements.txt at ./scripts/sphinx-pre-install line 305. The script simply expects to parse a version constraint with Sphinx in the requirements.txt. That version is used in the script for suggesting the virtualenv directory name. To suggest a virtualenv directory name, when there is no version given in the requirements.txt, one could try to guess the version that would be downloaded with 'pip install -r Documentation/sphinx/requirements.txt'. However, there seems no simple way to get that version without actually setting up the venv and running pip. So, instead, name the directory with the fixed name 'sphinx_latest'. Finally update the Sphinx build documentation to reflect this directory name change.
