An invalid token will lead to 404, eventually

[peterbe]

I was using a PAT that didn't have permission to read from the other repo. What happens is that you get a 404 which GItHub's way of saying you don't have access.

What this action "ought" to do is crash and burn instead of printing

Download `some-name` from: https://api.github.com/repos/owner/repo/actions/artifacts
Waiting... None 404
Waiting... None 404
Waiting... None 404
....

Then it becomes a lot easier to understand what's wrong with how you use the action.
