Add NodeToClientV_24 for ValidateTx query

[palas]

Description

Adds NodeToClientV_24 to the node-to-client protocol version enumeration, needed for the new ValidateTx query in the LocalStateQuery protocol.

Part of IntersectMBO/cardano-cli#1380.

Big picture: transaction validate currently applies applyTx client-side with an empty UTxO set, making it unable to properly validate transactions. This cross-repo change adds a new ValidateTx query to the LocalStateQuery protocol so the node validates transactions against its real ledger state and UTxO set.
