Currently if a post is written in Japanese (`ja`) and has been translated to English (`en`), a British (`en_GB`) user will see the Japanese post. WIth this PR we normalize user locales so the best match would show (`en` first, then `en_GB`, or `pt` and `pt_BR`). Note: `LocaleNormalizer` is from discourse-ai and will be removed there.
