fix: remove category prints

commands where the output is important `llama stack build --show-deps` (soon to be `llama stack show`) print some log.py `cprint`'s on _every_ execution of the CLI

These prints aren't necessary as the user is the one setting the logging config, they probably don't need to be alerted that these levels are being set
