In doing the release for v0.9.3, I found the following warning in the logs:
/home/runner/work/python-control/python-control/control/sisotool.py:161: MatplotlibDeprecationWarning: The join function was deprecated in Matplotlib 3.6 and will be removed two minor releases later.
[3339](https://github.com/python-control/python-control/actions/runs/3808966270/jobs/6480141305#step:6:3340)
ax_phase.get_shared_x_axes().join(ax_phase, ax_mag)
We should fix this at some point.
