Add docreader version to TransactionInfo model in process response

[liwocd]

docreader is returning version in TransactionInfo section in JSON (example from sample response below), but TransactionInfo model doesn't contain this information. I know that it is possible to obtain it within DeviceInfo model via ping endpoint, but it would be very useful to have this information for each processing response.

Example from sample response:

"TransactionInfo": {
    "ComputerName": "fc30e309c3b2",
    "DateTime": "2022-04-08T06:20:50.719Z",
    "SystemInfo": "Linux, fc30e309c3b2, 5.4.0-105-generic, #119-Ubuntu SMP Mon Mar 7 18:49:24 UTC 2022, x86_64",
    "TransactionID": "90ad213b-ff3d-415a-984d-fe36b04930df",
    "UserName": "",
    "Version": "6.2.157322.528"
  },
