      • Make WouldChangeOwningShard error have a "supportInternalTransactions" flag that is set to true if the mongod throwing the error (on original owning shard) is in FCV latest.
      • Make mongos will fallback to the previous implementation of WouldChangingOwningShard handling upon seeing this flag or a InternalTransactionNotSupported error after trying to handle the error using internal transactions.
