Context:

During the conversations with the WMF we were asked some questions about the Wikibase Ecosystem and gathered some stats inspired by these talks.

Acceptance criteria:

• rework aggregated stats re major and minor versions
• aggregate users (general accounts and zoom-in on admins as a special sub category)
• create metric for age of instance based on first log date
• pull total number of triples for instances with known sparql endpoints, and aggregate it
