feat(localization): add Ukrainian language support

Adds support for the Ukrainian language in the app. Updates the 
LocaleUtils class to include Ukrainian localization, adds the 
appropriate string resource for Ukrainian, and modifies the 
locales list to recognize Ukrainian as a valid language option. 
These changes enhance the app's accessibility for Ukrainian 
speakers.
