gh-151678: Add tests for tkinter.scrolledtext (GH-151753) Add a test for the ScrolledText widget, which had no tests: that it is a Text widget held in a Frame with a Scrollbar, that Text methods work, that the geometry manager methods are redirected to the frame while configure is not, and that the scrollbar tracks the text view.
