ErrorCode description should be localized

[ronyfadel]

RevenueCat's RCPurchasesErrorCode is directly displayed to hundreds of thousands of users daily. It's a shame that the errors aren't localized.

Furthermore, some errors (e.g. storeProblemError) have underlying errors which would warrant a better localized description (such as 'no network connection' or any other storekit error)

Hey @ronyfadel! Definitely valid feedback. Breaking it down into two components:

• storeProblemError: yeah, this is fairly generic. Jacob told me about the issue you were having, I would have expected those to be translated into RC's paymentNotAllowedError, which would have been much more informative. Any chance you have logs and sysdiag for them? The expected behavior from StoreKit is that they'd send a paymentNotAllowed, but ASDErrorDomain errors are undocumented. We've captured a few manually and do some translation, but they can be hard to track down. If you send me logs, I'm happy to file a radar and get the codes mapped more nicely to paymentNotAllowed.

• Errors that would warrant better localized description: absolutely agree. We've historically relied on returning error codes, and expecting developers to translate the messages into something user-friendly themselves, but, this feels like an outdated assumption at this point. A lot of devs just want an easy way to display an error to a user, and it's something we could do. We've had a tough time with proper localization for paywalls, but I'd like to find a way to do it nicely on behalf of all RevenueCat customers
