[mediawiki/extensions/Wikibase@master] Use Kartographer's <maplink> for Wikitext globe coordinates formatting

https://gerrit.wikimedia.org/r/450399

Do we expect any significant breakage in existing usage when this change goes out?

The feature is behind a configuration variable disabled by default. This change uses <maplink> instead of <mapframe> so the output is still a textual display of the coordinates, but now with a link that opens a Kartographer map. So, nothing should break except if some modules parses the output (but hopefully they all use #property for that)

Ok great. Thanks!

FYI @Lea_Lacroix_WMDE

\o/ @Tpt I think we should prepare an announcement for that. I'll draft something then you can correct me :)

The deployment have been done.

There is a small bug that may affect some Lua modules: calls mw.wikibase.entity:formatStatements().value using Lua may need to be passed to frame:preprocess to be properly display the <maplink> table. I have already fixed Module:Databox that was affected.

I have done a quick lookup on frwiki, cawiki and enwiki and I have not found any other module making use of it with globe coordinates. So I hope it is fine

Then I simply added a line to Tech News and to the Wikidata weekly. Feel free to edit if I wrote something inaccurate :)

I've edited to make it fit with the normal Tech News style; please make sure the information is still correct. (:

Is there an example of it live in action? If yes, please add it to the task description (for easy visibility) and maybe also the Tech News items? Thanks!

Wondering if that's the case in T218051: Raw <mapframe> code displayed in an infobox template when mapframe is not enabled on that wiki?

Is there example page for Lua/wikicode somewhere?

The same happens for the {{#statements:…}} parser function. IMO this is a huge problems and should be fixed fast. I've created T220122: Displaying mapframes for geocoordinate on client requires preprocessing by the user for this.

It seems that maplink being used without "zoom" parameter is causing problems, see T225350.
