Description:

In latest develop build, at the language selection dropdown, we see some language not recognized by tap-i18n so they are displayed as: lc-CC (for example: vi-VN, th-TH) instead of the human-friendly language name.

AFAIK, tap-i18n uses a language name lookup list to infer the language name. If the i18n.json files are named with unregconized code, the raw file name is displayed instead (so vi-VN.i18n.json -> vi-VN...).

My suggestion is to rename these files to comply with tap-i18n's language table. If this is not possible, maybe we have to add a tap-project.i18n file to list the languages explicitly.

I'm attempting the latter approach in a fork but am getting error with tap-i18n and still figuring how to get it work.
