[3.9] gh-114021: Pin various sphinxcontrib extensions to older versions (GH-114022)

[AA-Turner]

(cherry picked from commit 94b1d1f)

• Issue: Doc build errors in CI due to updated sphinxcontrib-applehelp #114021

[m-aciek]

Suggested change

Jinja2<3.2

this constraint is superfluous; there's jinja2==3.0.3 in requirements.txt

[AA-Turner]

This is a backport, minimal changes are preferable.

We are introducing constraints.txt, I am wondering if we shouldn't convert current pins in requirements.txt of transitive dependencies to constraints.

# Docutils version is pinned to a version compatible with Sphinx # version <3.5.4. It can be removed after bumping Sphinx version to at # least 3.5.4. docutils==0.17.1 # Jinja version is pinned to a version compatible with Sphinx version <4.5. jinja2==3.0.3 # Alabaster version is pinned to a version compatible with Sphinx version 2.4.4. alabaster==0.7.13 

into

# docutils 1.18 is incompatible with Sphinx <3.5.4 docutils<1.18 # jinja2 3.1.0 is incompatible with Sphinx <4.5 jinja2<3.1.0 # alabaster 0.7.14 is incompatible with Sphinx 2.4.4 alabaster<0.7.14 

in constraints.txt for consistency.
