DOC: Linux Devdocs workflow requires installing packages that don't exist

[fuglede]

Reproducing Code Example

In the development quickstart, one of the steps requires you to run

conda create --name scipydev python=3.8 numpy pybind11 cython pythran pytest gfortran_linux-64 gxx_linux-64 sphinx pydata-sphinx-theme sphinx-panels matplotlib mypy git

This fails since none of pythran, sphinx-panels, or pydata-sphinx-theme can be found. Using -c conda-forge seems to help.

Thanks @fuglede, indeed the information is correct for macOS but missing here. Would you make a PR to harmonize this?

[fuglede]

Yep, done.
