DeprecationWarning from Numpy 1.24.0 due to usage of np.bool8

[jonyscathe]

Getting a DeprecationWarning on /usr/local/lib/python3.11/site-packages/plotly/express/imshow_utils.py:24 due to use of deprecated type np.bool8.

Hopefully it is as simple as just removing line 24 from this file, as dtype_range in scikit-image only has np.bool_ and not np.bool8, but I'm not 100% sure what is needed here.
