Print GHA log groups to stdout instead of stderr

In all other places (e.g. `bootstrap.py`, `opt-dist`), we use stdout instead of stderr. I think that using stderr might be causing some discrepancies in the log, where sometimes the contents of a group "leak" outside the group. Let's see what happens if we use stdout instead. It's possible that it will be worse, since we print most stuff to stderr (?).
