Subject: [PATCH] Cover every supported language in ContentLanguage detection
 tests

Extend the homepage-language detection dataset to assert all 15 supported
languages resolve from their <html lang> subtag, and pin the primary-subtag
matching so a malformed tag ("english") no longer resolves via a two-letter
prefix.
