Note:
This will require changes made to the addons-server API call, specifically with the lang query parameter (which is currently hard-coded as en-US). Using / defaulting to the system locale will probably be the easiest action for now (can use os-locale).
Don't want to restrict
amo-cli
to just English speakers / readers - localizing the app using 🌐 i18n should be on the roadmap 👍
