Fix #100652: Correct Shortcut Hovering Editor Type Button

When hovering over the "Editor Type" button it always shows Shift-F1 as
the shortcut no matter what the current Editor Type is. We already have
specific code for "SCREEN_OT_space_type_set_or_cycle" for the items on
the popup menu, but it doesn't handle the case of hovering the menu
itself. This adds just adds a line to handle this.
