gwpy.io.nds2 fails to load on Python 3.11

When attempting to test on Python 3.11 I get this:

>>> import gwpy.io.nds2
/home/duncan/git/gwpy/gwpy/plot/gps.py:28: MatplotlibDeprecationWarning: The matplotlib.docstring module was deprecated in Matplotlib 3.6 and will be removed two minor releases later.
  from matplotlib import (ticker, docstring)
ValueError: 3 is not a valid Nds2ChannelType

During handling of the above exception, another exception occurred:
