I started off this way in #907, then switched to nominatim, but our
current usage appears to be a violation of the nominatim terms of
service. Geocodefarm doesn't seem perfect, but given my reading of their
terms of service, I think using it in our examples in docs is okay.
The request to google is frequently (always?) failing in the past few
months, so use geocodefarm instead for the example of how to use
geocoding in geopandas.
