I updated this PR to add

      - uses: conda-incubator/setup-miniconda@v2
        with:
          python-version: ${{ matrix.python-version }}
          miniforge-version: latest
          use-mamba: true

which seems to fix the macOS issue.

and also added ipykernel to docs deps, which is now needed for nbsphinx: https://nbsphinx.readthedocs.io/en/0.8.2/installation.html#Jupyter-Kernel
