Add comments in custom transformer

[steinybot]

I want to be able to add comments at the end of a line in step as part of a custom transformer.

For example:

transform "artifacts.junit" do |item|
  {
    name: "Publish JUnit Report",
    uses: "mikepenz/action-junit-report@v5.3.0",
    if: "success() || failure() # always run even if the previous step fails",
    with: {
      report_paths: "**/junit-reports/TEST-*.xml"
    }
  }
end
