Subject: [PATCH] toYaml - Fixes #3470 - trailing \n issue

`toYaml` was introducing a new line. It is an issue since the new line is part of a functions output, it can't be whitespace chomped away so it would require a `trimSuffix "\n"` pipe. This commit trims one trailing `\n` from the toYaml output.

(cherry picked from commit 6cdf6cee56dcd90e3dca82950b15d46e6bb4587b)
