Support Traditional Chinese translations

[jaller94]

As pointed out in the delivered idea to support Chinese, Traditional Chinese is different enough to require its own translation language. https://connect.mozilla.org/t5/ideas/support-chinese-translations/idi-p/33405?search-action-id=30537...

Support for traditional Chinese as used in Hong Kong and Taiwan has also been requested on the Community Forum. https://support.mozilla.org/en-US/questions/1526303

The user @Eeeee already seems to have done some work. https://connect.mozilla.org/t5/ideas/platform-for-contributing-translation-data/idi-p/96792
