- Fix locale key in lang-list.json from "locale-ie-GA" to "locale-ga-IE"
to match the actual locale code used in IntlProvider
- Add ga -> ie mapping in getFlagCodeForLocale() so the Ireland flag is
shown instead of the Gabon flag
- Add missing ["ga", "ga-IE"] entry to check-locales.cjs validation list
