Setting log_level to WARNING still shows info messages (dev UI)

Running adk web --log_level=WARNING shows a lot of info messages that clutter the logs.

INFO:     Application startup complete.
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

The info messages are even more verbose in a containerized dev environment.

I've locally tested a one-line change to add log_level=log_level.lower() to uvicorn.Config() (jedick@b9ac2c4).

Could this be considered for merging into the main codebase?
