Revert AAE-46242 crowdin locale mapping changes (#11949)

Reverts the following commits:
- 80e9e51cfa AAE-46242 - Looks like we need to override the mapping as crowding config is not set to this format
- 345e1e69ad AAE-46242 - should use the variable osx_locale to match the format xx-YY
- a2b026ed7e [AAE-46242] - Changed the name convention for translation files to ISO standard naming
