feat!: Add Version information to ChangeDataFeedIncompatibleSchema

[OussamaSaoudi]

Please describe why this is necessary.

While performing change data feed, our iterators may produce arbitrary Delta errors. However, a consumer likely wants to know the exact version that caused the CDF error so that they can retry their request with a new version.

Example:
cdf(1...10)
version 5 fails!
retry: cdf(5..10)

Describe the functionality you are proposing.

Add a Version field to Error::ChangeDataFeedIncompatibleSchema. Update this enum variant to a struct type with clear field names.

Thanks @OussamaSaoudi , I'd be happy to take a stab at this!
