Update: It was announced in WWDC 2022 that the priceLocale would be reintroduced in Product. However the latest version of the beta SDK (Xcode 14.0 beta 2) does not contain it. A reference to a currency formatter style is introduced instead, with var priceFormatStyle: Decimal.FormatStyle.Currency which should allow formatting calculated user-facing strings.
