Add pre-commit hook to check the logger

[leseb]

🚀 Describe the new functionality needed

We have our own logger implementation:

from llama_stack.log import get_logger
logger = get_logger(name=__name__, category="core")

Let's have a pre-commit hook that scans the code to make sure we use our logger and not do import logging.

💡 Why is this needed? What if we don't build it?

Consistent codebase.
