Trouble with building latest mne documentation locally

Before I will post it as a sphinx gallery issue, I would llike to ask here,
I have problem with building latest mne documentation locally (I would like to use it in Dash as a offline docset)
Running make html_stable results in

Configuration error:
Unknown key(s) in sphinx_gallery_conf:
'api_usage_ignore'
'show_api_usage'
make: *** [html_stable] Error 2

How the documentation should be otherwise build?

I think you probably need a newer version of Sphinx Gallery. Those keys were added fairly recently (in the last 6 weeks or so?) by @alexrockhill

and I suppose if this error is possible, it means we need to update our sphinx_gallery version pin in MNE-Python’s requirements_doc.txt. @alexrockhill can you check?
