gh-104497: Make tkinter test pass with tk 8.7

[terryjreedy]

For test_widgets.MenuTest.test_configure_type, the options in the error message change to alphabetical order.

• Issue: Tkinter: Tk 8.7 alphabetizes options in certain error messages #104497

[terryjreedy]

@chrstphrchvz please verify that this passes on 8.7.

@serhiy-storchaka I presume a root.destroy call is needed rather than merely deleting the python binding. If another test in the file ever needs a fix for 8.7 or 9.0, etc., fetching tk_version could be moved to the top of the file, or I could do so now if you prefer.

@chrstphrchvz Please verify that this run without error on 8.7.

@serhiy-storchaka If tk_ver were someday needed for another test, it could be moved to module level. I can do so now if you want.

I presume that explicit root.destroy is needed before exiting the function.

[chrstphrchvz]

I confirmed that the test passes on Tk 8.7 with this change.

[serhiy-storchaka]

You can use widget.info_patchlevel() in 3.11+, or test.test_tkinter.support.tcl_version or test.test_tkinter.support.get_tk_patchlevel() in older versions.

This PR was written specifically as it is because this was the only known test failure when written. #104855 and #104856 report more is test_widget and widget_test. I will later list the alternatives I see in the first of those issues.
