Minor: description of transaction doesn't return `from`

[janndriessen]

What piece of the framework are having the lack of docs?

The from field on transaction is not returned as expected when calling a description on a transaction.

To reproduct:

• Call description on a transaction that has the from field set.

You can see here that the issue that only sender is return as from when set: https://github.com/web3swift-team/web3swift/blob/develop/Sources/Web3Core/Transaction/CodableTransaction.swift#L274

What bit of docs would you like to have?

In general whoever takes this ticket could look at improving the description of a transaction.
