From what is written on https://wikitech.wikimedia.org/wiki/Analytics/Data_Lake/Edits/Geoeditors/Public, the Geoeditors Monthly dataset is only available for the Wikipedia projects (differents language versions). I looked for but I did not find any task on Phrabricator to ask for the same kind of data for non-Wikipedia projects (Wiktionary, Wikivoyage, Wikisource, etc). Maybe it may not be applicable to all Wikimedia projects but it is for some of them (the ones I have listed).
This is the equivalent of T238365, that cares only about Wikipedia data.
Sorry if one ticket is already for this task.
