Supplies translations for ConfigurableOperationDef descriptions and arg labels from the
server-side message catalogs. Implemented by the I18nService and provided under the
CONFIGURABLE_OPERATION_TRANSLATOR token.
interface ConfigurableOperationTranslator { getConfigurableOperationTranslation(languageCode: string, keyPath: string[]): string | undefined;}(languageCode: string, keyPath: string[]) => string | undefinedReturns the string stored at the given path within the configurableOperation namespace of
the catalog for languageCode, or undefined if there is no entry there. The value is
returned verbatim, without ICU formatting, since operation descriptions contain
{ argName } placeholders which are interpolated by the client.
