Register eleven new compliance-portal locales

Browse Source 
Add German, Spanish, Indonesian, Italian, Japanese, Korean, Polish,
Portuguese, Turkish, Ukrainian, and Simplified Chinese to
SUPPORTED_LANGUAGES, and map each one's browser language-tag prefix to
its canonical locale in resolveLanguage() so i18next can be asked to
load it. Catalog JSON for these locales lands in the following
commits.
