How do I differentiate between Version1 and Version2 blocks in the JSON RPC response of chain-get-block?

[devendran-m]

In the response, it could be either:

• result.block_with_signatures.block.Version1 followed by legacy block fields (pre-Condor)
  OR
• result.block_with_signatures.block.Version2 followed by new block fields(Condor)

P.S. - Answer / Explanation based on the details shared by @rafal-ch in a Slack conversation.
