CI failures in doctest, examples #1136

From #1135 (also in #1133):

I see two failures on CI , but I can't see that these changes caused them:

first, in doctest-linux: roryyorke/python-control/actions/runs/13612156165/job/38050709282

Traceback
=========

      File "/home/runner/miniconda3/envs/doctest-env/lib/python3.12/site-packages/sphinx/events.py", line 415, in emit
        raise ExtensionError(
    sphinx.errors.ExtensionError: Handler <function html_collect_pages at 0x7f36a35016c0> for event 'html-collect-pages' threw an exception (exception: module 'sphinx.util' has no attribute 'console')
which seems to be https://github.com/sphinx-doc/sphinx/issues/13352.

Then in install-examples: roryyorke/python-control/actions/runs/13612156159/job/38050709274
