Specs
known_locale_names() :: [Cldr.Locale.locale_name(), ...]
The configured locales for which plural rules are defined.
Returns the intersection of MyApp.Cldr.known_locale_names/0 and
the locales for which Ordinal plural rules are defined.
There are many Cldr locales which don't have their own plural
rules so this list is the intersection of Cldr's configured
locales and those that have rules.
