[issue32940] IDLE: pyparse - replace StringTranslatePseudoMappingTest with defaultdict

[Cheryl Sabella]

New submission from Cheryl Sabella <chekat2 at gmail.com>:

Based on timing test on msg312733, StringTranslatePseudoMappingTest and a defaultdict have about the same performance, so this replaces the custom class with the stdlib functionality.
