Create a new section "Points" after "Mask layer" (nice to have)

IMHO, it makes more sense to add the example of geopoints via QID to the existing section "Via Wikidata ID" and the example of a query to the existing section "Via Wikidata query"

I adjusted the existing example for geopoints to contain images in addition to title and description. I wanted to link to articles as well but data in the example does not have article pages. We could add another query for this. But since the geoshapes query already contains this information I did not look for one. But I added a general information about how adding links and images works. https://www.mediawiki.org/wiki/Help:Extension:Kartographer#Via_Wikidata_query I hope this covers all relevant information for now.
