Service exec output should separate stdout and stderr

[praetoriansentry]

Background & motivation

In the example above, I'm using kurtosis service exec to grab the content of a file. At the top of the standard output I get "The command was successfully executed and returned '0'. Output was:" In order to pass this data to a parser like jq, I need to trim off the top line.

Desired behaviour

It would be great if the actual output was written to standard output via out.PrintOutLn and if the log message was written to standard error via out.PrintErrLn.

This would just simplify some scripting / automation on top of Kurtosis cli

How important is this to you?

Nice to have; this feature would make using Kurtosis more enjoyable.
