Fix broken main with static checks

[kaxil]

#43281 changed the python exec path and is now failing with:

Traceback (most recent call last):
  File "/home/runner/work/airflow/airflow/./scripts/tools/check_if_limited_dependencies.py", line 46, in <module>
    check_call([sys.executable[0], DEV_BREEZE_SRC_PATH / "airflow_breeze" / "breeze.py", "--help"], env=env)

That is because:
