Update documentation according to #6294

[Muhammad-Altabba]

The final outputs of #6294 need to be documented.

A new parameter, fillInputAndData, was added to the options argument for formatTransaction. This method is used for formatting both user submitted and RPC response transaction objects. So, we need a flag to determine whether to leave the transaction object as given, or fill in the input or data properties if they weren't present. The fillInputAndData option is set in rpc_method_wrappers.ts for relevant methods
