Partially addresses #3061

There are a few accidental renames that weren't suppose to happen,other than that it looks pretty good

This is looking very good. I noticed some more stuff that can be improved upon the second review. It would also be nice to make pattern synonym record names for [Era]TxBody constant for all eras as well. For example AlonzoTxBody is defined as:

pattern AlonzoTxBody
  { inputs,
    collateral,
    outputs,
    txcerts,
    txwdrls,
    txfee,
    txvldt,
    txUpdates,
    reqSignerHashes,
    mint,
    scriptIntegrityHash,
    adHash,
    txnetworkid
  }

But it should be something like this:

pattern AlonzoTxBody
  { atbInputs,
    atbCollateral,
    atbOutputs,
    atbCerts,
    atbWdrls,
    atbTxFee,
    atbValidityInterval,
    atbUpdate,
    atbReqSignerHashes,
    atbMint,
    atbScriptIntegrityHash,
    atbAuxDataHash,
    atbTxNetworkId
  }

We want to make sure that there are not a dozen different names for a similar concept (eg txUpdates vs atbrTxUpdate or _txUpdate prior to this PR - note that one is plural another one is not)

I guess the goal is to have no ambiguity between era and the least amount of discrepancy between record fields for the raw type, the actual newtype wrapper around it as well as the lens names for the corresponding fields.

Sorry, more review comments. I am truly enjoying seeing this cleanup!

Looks awesome. Thank you!
