Feature summary (what you would like to be able to do and where):
Programming language names often look the same for languages, but as can be seen on Wikidata item for e.g. JavaScript (https://www.wikidata.org/wiki/Q2005#sitelinks-wikipedia), there are languages that write that name with the national alphabet. It would be nice if Wikifunctions displayed the prog. language's name for these users as they are used to it and not in English.

Or, as with function composition, expose a translatable message for JavaScript and Python (and perhaps other, future languages in due time).

Benefits (why should this be implemented?):
Better i18n of Wikifunctions
