🐛[Bug] Export DiscountsI18nProvider or have Appprovider accept currency or i18n manager

[vincaslt]

Issue summary

AppProvider creates i18n context, but it doesn't allow passing currency or the default manager. Best would be to export DiscountsI18nProvider and let people use that, because if they already use the AppProvider from i18n package, discount provider interferes and resets the manager.
