Provide easier way of accessing metrics such as active editors as defined in Wikistats 1
We were looking at numbers for editors on Wikidata on Wikistats 2. These numbers do not seem to match with the stats we have elsewhere. The number of editors who made at least one edit is twice at high as it probably should be.
https://stats.wikimedia.org/v2/#/wikidata.org/contributing/editors shows about 36000 editors
Compare with https://stats.wikimedia.org/wikispecial/EN/TablesWikipediaWIKIDATA.htm and second graph on https://grafana.wikimedia.org/dashboard/db/wikidata-site-stats?orgId=1&from=now-1y&to=now where it is about 19000. This also matches Special:Statistics on Wikidata.
A similar issue is present for German Wikipedia. We didn't check other sites.
