fix: add type param to ledger & ledger_data (#2503)

- Add missing `type` param
- Clean up typing of `type` param and the response property
`account_objects` of the `account_objects` request
- Create interfaces `HasPreviousTxnID` and `MissingPreviousTxnID`. This
helps clean up type checking with regard to the presence of
`PreviousTxnID` and `MissingPreviousTxnID`
