The statistics page should list the number of stars

[egonw]

Is your feature request related to a problem? Please describe.
No, just a small enhancement. I can make the patch, if we agree. The current statistics page lists the number of a large number of things, but the number of stars in is not listed, with some 3.2M a good part of the main SPARQL endpoint: https://w.wiki/CdB9

Describe the solution you'd like
Add a line on the https://scholia.toolforge.org/statistics listing the number of stars. E.g. with a query like this:

SELECT (COUNT(DISTINCT ?o) as ?count) WHERE {
  ?o wdt:P31 wd:Q523.
}

Describe alternatives you've considered
An alternative query is to include subclass of too, which would increase the count by some 1.2M, see https://w.wiki/CdBL
