Add version check for k8s setup venv command (#36673)

This command install airflow in k8s venv and in case version of
Python is not yet supported by Airflow, it might fail.

We do not have check it lower-bound because breeze supports the
same minimum version of Airflow as Airflow itself.

The command prints instructions on how to reinstall breeze with
different Python version in such case.
