[FR] - `TxVotingProcedures` accepts `ScriptWitness` but not broader `Witness` type

*External*

**Area**
Transaction building.

**Describe the feature you'd like**
Constructors such as `TxWithdrawals`, `TxCertificates` accepts `Witness` under `BuildTxWith` but [`TxVotingProcedures`](https://github.com/IntersectMBO/cardano-api/blob/9386533b1c9f5e262287d4cca6dbaad4d4365eec/cardano-api/internal/Cardano/Api/Tx/Body.hs#L1289) utilizes `ScriptWitness` which does not include key witnesses. Is this deliberate? Is it that key witnesses don't make sense in this context? If key witnesses make sense for voting procedures, then not including them may mess up with functions like `estimateTransactionKeyWitnessCount`.
Thanks!
