TypeError: unsupported operand type(s) for |: 'type' and '_GenericAlias'

Hi,

Trying to run vtk-widgets example and I get an error:

Traceback (most recent call last):
  File "D:\dev\vtk_widgets_clip.py", line 23, in <module>
    from trame_vtk.modules.vtk.widget import WidgetManager
  File "D:\dev\venv\lib\site-packages\trame_vtk\modules\vtk\widget.py", line 107, in <module>
    WidgetParam = vtkAbstractWidget | Type[vtkAbstractWidget]
TypeError: unsupported operand type(s) for |: 'type' and '_GenericAlias'

vtk-widgets version: 2.8.10

That specific example require Python 3.10 because of the type annotation. (FYI @alesgenova )
