sphinx-build fails: setuptools not included in requirements_doc.txt

[sjswerdloff]

Apple M1, MacOS 14.6, python 3.12.4
and I have in my .zshrc:

source $HOME/zsh-autoswitch-virtualenv/autoswitch_virtualenv.plugin.zsh

so... a virtual environment that got built automatically when I cd in to the dicomweb-client directory...

sphinx-build -b html docs/ docs/build/
Running Sphinx v5.3.0

Configuration error:
There is a programmable error in your configuration file:

Traceback (most recent call last):
File "/Users/stuartswerdloff/.virtualenvs/dicomweb-client-crgx/lib/python3.12/site-packages/sphinx/config.py", line 350, in eval_config_file

import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'

pip install setuptools
resolved the issue. Is this something that could be added to requirements_doc.txt (without creating issues for others)?
