This is used to return an image legend from Wikidata

Call as {{#invoke:Wikidata |getImageLegend | <PARAMETER> | lang=<ISO-639code> |id=<QID>}}
Returns PARAMETER, unless it is equal to "FETCH_WIKIDATA", from Item QID (expensive call)
If QID is omitted or blank, the current article is used (not an expensive call)
If lang is omitted, it uses the local wiki language, otherwise it uses the provided ISO-639 language code
ISO-639: https://docs.oracle.com/cd/E13214_01/wli/docs92/xref/xqisocodes.html#wp1252447

Ranks are: 'preferred' > 'normal'
This returns the label from the first image with 'preferred' rank
Or the label from the first image with 'normal' rank if preferred returns nothing
