I am unable to identify an error in the CI jobs docs, except perhaps this warning that seems unrelated:

/home/docs/checkouts/readthedocs.org/user_builds/xray/conda/8375/lib/python3.10/site-packages/cartopy/io/__init__.py:241: DownloadWarning: Downloading: https://naturalearth.s3.amazonaws.com/50m_physical/ne_50m_coastline.zip
  warnings.warn(f'Downloading: {url}', DownloadWarning)

Besides I am actually able to download https://naturalearth.s3.amazonaws.com/50m_physical/ne_50m_coastline.zip.

This warning is also unrelated as far as I can see, but should be addressed in some other PR:

WARNING: The default value for `navigation_with_keys` will change to `False` in the next release. If you wish to preserve the old behavior for your site, set `navigation_with_keys=True` in the `html_theme_options` dict in your `conf.py` file.Be aware that `navigation_with_keys = True` has negative accessibility implications:https://github.com/pydata/pydata-sphinx-theme/issues/1492

See pydata/pydata-sphinx-theme#1492 for an explanation and PR #8379 to fix this warning.
