Merge bitcoin/bitcoin#26777: rpc: Remove duplicate field in RPCHelpMan for gettransactions

090ad51 rpc: Remove duplicate field in RPCHelpMan for gettransactions (Joshua Kelly)

Pull request description:

  The field 'comment' appears twice in `TransactionDescriptionString`, incorrectly - this commit removes the instance of the comment field without a description, preserving the one with a description.

  On master, the duplicate fields can be be viewed here: https://github.com/bitcoin/bitcoin/blob/master/src/wallet/rpc/transactions.cpp#L419-L423

  `TransactionDescriptionString` is included in RPC calls such as `listtransactions` which have functional tests.
