Remove unnecessary __init__ override in GoogleJsonSchemaTransformer

The __init__ method was just calling super().__init__() with the same
parameters, providing no additional functionality. The base class defaults
are exactly what we need:
- prefer_inlined_defs defaults to False (native $ref/$defs support)
- simplify_nullable_unions defaults to False (type: 'null' support)
