Let Product Opener use and cache Wikidata data for entities

[teolemon]

Who for

• Open Food Facts mobile developers
• Users

Why

• Wikidata provides expanding structured and non-structured info in many languages
• Many taxonomy entries are linked to Wikidata, but we're not using it to the fullest.
• Wikidata is volatile, and entries may change, disappear, or may be vandalized for a period of time

How

• Create a Wikidata caching system that fetches data about entities and stores them on the server
  • Run periodically the Wikidata harvesting script #6475
• Harvest properties from List of Wikidata properties we can display on Knowledge panels for Categories #1022
• Expose Wikidata information for consumption within the Knowledge panel API #6248
• Use the Knowledge panel API to enrich the product page

Part of

• 📖 Knowledge panels (Tracker) #5493
