`i18n.supportedLocales` is deprecated in favor of `i18n.extraLocales`,
and it seems you are using `i18n.supportedLocales` and forgot to
include some locales specified in `i18n.defaultLocale`,
`i18n.extraLocales` or `i18n.extraLocaleSettings`.
If you're trying to install additional locales not specified in
`i18n.defaultLocale` or `i18n.extraLocaleSettings`, consider adding
only those locales to `i18n.extraLocales`.
