Use `logger.info` instead of `print` to emit a logging message in `hub.py`

# What does this PR do?

I found a line that uses the `print` method to emit a logging message in `transformers/utils/hub.py`. When I was developing a CLI app that outputs results in a specific format to stdout, this line emitted a logging message to stdout, resulting in an error. This PR fixes the line to use the `logger.info` method to emit the message instead.
