As a customer, when I access the MR API endpoint, I want the JSON to include the WIkidata statements for the related page entity

Subtask As a first step to speed up Wikidata API, I'll investigate caching of P___ property labels and descriptions in EN (maybe more languages) so we can avoid multiple trips to WIkidata APIs for labels.

I'll parser this HTML page to collate the PID and labels in a Golang map (or Redis cache): https://www.wikidata.org/wiki/Wikidata:Database_reports/List_of_properties/all

• Add the Wikidata entity statements to the MR API
• Add filtering so the statements can be removed from the API
• Run a performance test to see how long it takes for the new JSON to be sent for one REST request
