Code Review

This pull request modifies the DisputeEventNotification and DisputeNotificationRequest models to enhance enum deserialization by providing a fallback cast for raw string values. The review identifies potential issues with casting nullable strings to non-nullable enums, which could trigger compiler warnings, and highlights a risk where a non-nullable property might be assigned a null value during deserialization.

The cast (DisputeEventNotification.TypeEnum)typeRawValue is to a non-nullable type, which may trigger a compiler warning since typeRawValue can be null. It is safer and more consistent with the Option<TypeEnum?> wrapper to cast to TypeEnum?.

                            type = new Option<DisputeEventNotification.TypeEnum?>(DisputeEventNotification.TypeEnum.FromStringOrDefault(typeRawValue) ?? (DisputeEventNotification.TypeEnum?)typeRawValue);

The property Type is defined as non-nullable, but type.Value can be null if the JSON contains "type": null. Using the null-forgiving operator ! suppresses the compiler warning but allows an invalid null state for a required property. Consider adding a null check or making the property nullable to ensure robust handling of null values in the JSON payload.
