Hi @robstoll, I was not sure if removing TestNG runner stack frames should be added to the project. I thought it would be good to add it in this PR when I was searching the repository for kotest usages.

Please let me know if it should be part of the PR or if I should exlude it completely or create new PR for that one change.
