Work around apparent false positive mypy bug.

Mypy is flagging contextMenuEvent signature problems.  This method does not
have an optional event parameter.

See:
* python/mypy#16437
* https://doc.qt.io/qt-6/qwidget.html#contextMenuEvent
* https://wiki.python.org/moin/PyQt/Handling%20context%20menus

The mypy error looks like this:

setoolsgui/widgets/views/treewidget.py:15: error: Argument 1 of "contextMenuEvent" is incompatible with supertype "QAbstractScrollArea"; supertype defines the argument type as "QContextMenuEvent | None"  [override]
        def contextMenuEvent(self, event: QtGui.QContextMenuEvent) -> None:
                                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
setoolsgui/widgets/views/treewidget.py:15: note: This violates the Liskov substitution principle
setoolsgui/widgets/views/treewidget.py:15: note: See https://mypy.readthedocs.io/en/stable/common_issues.html#incompatible-overrides
setoolsgui/widgets/views/treewidget.py:15: error: Argument 1 of "contextMenuEvent" is incompatible with supertype "QWidget"; supertype defines the argument type as "QContextMenuEvent | None"  [override]
