`connectors login` required before `connectors <command group> --help`, but error message doesn't say so

Bug Description

When installing the connectors CLI locally from main, if you don't run login first, none of the commands with --help will work and the error message is confusing.

To Reproduce

Steps to reproduce the behavior:

1. Go to connectors repo in a new virtual environment (python -m venv .venv)
2. Install CLIs locally (make install or pip install -e .)
3. Try --help on one of the connectors commands like connectors job --help
4. See error .cli/config.yml was not found. Make sure that the config is either present at the default location (.cli/config.yml) or it's passed via the '-c' or '--config' option.

Expected behavior

--help commands should ideally work without login, but if not possible we should prompt the user to run connectors login first.

Optionally, as @seanstory suggested, it would be nice if we can default to calling login in the background with default credentials, such as elastic & changeme in order make the UX a bit smoother.
