[issue22061] turtledemo doesn't launch due to changes in tkinter

[Lita Cho]

New submission from Lita Cho:

I updated my source code, and it looks like turtledemo doesn't launch anymore. I get the following error:

Traceback (most recent call last):
  File "/Users/litacho/Development/cpython/Lib/runpy.py", line 170, in _run_module_as_main
    "__main__", mod_spec)
  File "/Users/litacho/Development/cpython/Lib/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/Users/litacho/Development/cpython/Lib/turtledemo/__main__.py", line 328, in <module>
    main()
  File "/Users/litacho/Development/cpython/Lib/turtledemo/__main__.py", line 324, in main
    demo = DemoWindow()
  File "/Users/litacho/Development/cpython/Lib/turtledemo/__main__.py", line 124, in __init__
    self.mBar.tk_menuBar(self.ExamplesBtn, self.OptionsBtn)
AttributeError: 'Frame' object has no attribute 'tk_menuBar'

I dug into it and it looks like tk_menuBar was removed due to a fix in issue4350. If tk_menuBar needs to be removed, what method does turtledemo need to call instead to propagate its panels?
