matplotlib==3.3.1, is an older version that doesn't have the __version_info__ attribute. The matplotlib_inline package (used by Jupyter) is trying to use this attribute which was only added in matplotlib 3.5.0.
The __version_info__ attribute was added in matplotlib 3.5.0, so any version >= 3.5.0 will work with the matplotlib_inline package that Jupyter uses.

And monain and itk-elastix to be consistent with examples/requirements.txt. To address binder build where matplotlib fails to build from source. Similar to #359 Update the matplotlib version so pre-built packages are available.
