Description
In #627 new information was added about using the make_napari_viewer fixture.
However, we already have a section on make_napari_viewer:
https://napari.org/dev/developers/contributing/testing.html#make-napari-viewer
We should either link to it from this new info, or better yet, put this new info under that heading so it can be more easily located. Splitting important things over two locations seems less than ideal.
