[3.12] Bump some docs dependencies to resolve a Dependabot security alert (GH-107341) by miss-islington · Pull Request #107342 · python/cpython

Hmm. The Docs (Oldest Sphinx) job is failing:

make: Entering directory '/home/runner/work/cpython/cpython/Doc'
mkdir -p build

Missing the required blurb or sphinx-build tools.
Please run 'make venv' to install local copies.

make: *** [Makefile:49: build] Error 1
make: Leaving directory '/home/runner/work/cpython/cpython/Doc'

The same job succeeded on the PR to the CPython main branch (#107341). @hugovk, any ideas?

Ah! Possibly because #105368 wasn't backported?

Yes, looks like that was it. The CI was trying to install incompatible versions of requests and urllib3 at once.
