Fix airflow-ctl mypy static check on the 0.1 branch

[Lee-W]

The same test-to-stable sync (#67294) repointed the mypy-airflow-ctl hook at ../scripts/ci/prek/run_mypy_full_dist_local_venv_or_breeze_in_ci.py, which only exists on main. On this branch prek dies before mypy ever runs:

error: Failed to run hook `mypy-airflow-ctl`
  caused by: Run command `python hook` failed
  caused by: No such file or directory (os error 2)

Point it back at mypy_local_folder.py, which is what airflow-core, task-sdk, devel-common and dev/scripts all use on this branch.

Split out of #70724 so that PR stays workflow-only.

Thanks! Perhaps we can update the airflow/.github/boring-cyborg.yml as follow-up?
