TransactionByteFee doesn't exist anymore

[FrankBevr]

Problem

If you are following the docs, you encounter the const section .
You are typing happily the examples in your editor.
You assume you get something but you get undefinded
You have to start to tinker, ok, but UX decreases.

Solution

The closest that i can find is operationalFeeMultiplier.

const wsProvider = new WsProvider("wss://rpc.ibp.network/polkadot");
const api = await ApiPromise.create({ provider: wsProvider });
async function getOperationalFeeMultiplier(){
  //A fee mulitplier for Operational extrinsics to compute "virtual tip" to boost their priority
  const logy = await api.consts.transactionPayment.operationalFeeMultiplier.toString();
  console.log(logy);      
}
getOperationalFeeMultiplier()

I assume that the examples are in some way relevant.
In this case I dont think it its relevant and would just delete this line

Same with this line , because it took me a while to understand that babe exist on Polkadot, but the most parachains dont have this const.
