Make sure we always reset the code action widget context when the widget is hidden (microsoft#162278)

Make sure we always reset the `ctxMenuWidgetVisible` widget context when the widget is hidden

We've seen a handful of reports of keybindings not working. I'm not able to repo this, but the root cause may be that code action's context keys are not being cleared properly

This fixes it to make sure we always reset the context when the widget is closed
