Storefront API @inContext directive supports languages

As of version 2022-04, the @inContext directive in the Storefront API accepts a language argument in addition to country. If the requested language is active for the given country, as configured within the shop's Market settings, then the query will return translated values.

The list of available languages can be accessed with this query:

query Localization @inContext(country: CA, language: FR) {
  localization {
    # for the current country
    availableLanguages {
      isoCode
      endonymName
    }
    # and for non-current countries
    availableCountries {
      isoCode
      name
      availableLanguages {
        isoCode
        endonymName
      }
    }
  }
}

If an unsupported language or country is requested via @inContext, the response will fall back to supported values. In all cases, the actual country and language context will be returned as a response extension.
