bpo-42508: Remove bogus idlelib.pyshell.ModifiedInterpreter attribute (GH-23570) (GH-23571)

restart_subprocess is a method of self, the pyshell.InteractiveInterpreter instance. The latter does not have an interp attribute redundantly referring to itself. (The PyShell instance does have an interp attribute, referring to the InteractiveInterpreter instance.)
(cherry picked from commit e41bfd15dd)

 Any container can be passed as the *choices* value, so :class:`list` objects,
 :class:`set` objects, and custom containers are all supported.
-This includes :class:`enum.Enum`, which could be used to restrain
-argument's choices; if we reuse previous rock/paper/scissors game example,
-this could be as follows::
