build: avoid error in `build-packages-dist.sh` (#32923)
build: avoid error in `build-packages-dist.sh` (#32923)

Not sure why it works on other people's environments, but after
217db9b21 I started getting the following error when running
`scripts/build-packages-dist.sh` (on Windows):

```

SyntaxError: invalid syntax
```

It seems expected, because `print` is not a function, so
`print(foo, *args)` is interpreted as printing a tuple (where `*args` is
invalid syntax). Not sure why it doesn't break on other people's
machines :/

This change makes the verbose logs a little less pretty, but that
shouldn't be a big issue (given that it is an opt-in feature and it can
always be overwritten locally, if necessary).
