It was deliberate in the sense that I would allow them to write useful
messages to the Actions log. If they want to do nonsense like
"::set-output", then it's their foot and their gun.

I don't know if Actions distinguishes between stdout and stderr here
(i.e., if we redirected the script's stdout to stderr, would that
prevent this case or not?).
