Propose changing the défaut contribution language when switching countries

[teolemon]

Problem

From Yaron: "Hey everyone, I wanted to raise a concern about the app and web behavior; most of the products documented in Israel have their image tagged as English, even though the product is clearly in Hebrew. Is there a way to configure a default language for image tagging in the app? Is there an easy way to change the language using the web interface? Thanks :)"
