Steam parser: Use mul for titles

[lhulbert]

Utilising the mul language for titles will help reduce a lot of redundant labels on items.

I imagine you'd want a better solution that can actually handle games that have titles in multiple languages, but I've been using this hacky solution in my own install:

WikidataBot/steam_parser.py

Line 887 in 3190795

{ "labels": labels, "descriptions": descriptions },

->

 { "labels": {"mul": title}, "descriptions": descriptions },
