chore(pre-commit): add pre-commit hook to enforce llama_stack logger usage (#3061)

# What does this PR do?

This PR adds a step in pre-commit to enforce using `llama_stack` logger.

Currently, various parts of the code base uses different loggers. As a
custom `llama_stack` logger exist and used in the codebase, it is better
to standardize its utilization.
