Release 3.9.1 - Payment Request Product Type and Subtype to nullable

[david-ruiz-cko]

This release the Product model to use strongly-typed enums for the type and sub_type fields and ensures that these enums serialize to lowercase strings, improving consistency and type safety. It also introduces a comprehensive test suite to verify correct serialization behavior, including handling of None values.

Model and Enum Refactoring

• Introduced a new ItemType enum and updated the Product class to use ItemType and ProductSubType enums for the type and sub_type fields, respectively, instead of plain strings. The enums now serialize as lowercase values for consistency. (checkout_sdk/payments/payments.py, checkout_sdk/payments/payments.pyR627-R643)
• Updated the ProductSubType enum values to be lowercase, aligning with serialization expectations. (checkout_sdk/payments/payments.py, checkout_sdk/payments/payments.pyR627-R643)

Serialization and Testing

• Added a new test module product_serialization_test.py with tests to ensure that Product serializes type and sub_type fields as lowercase strings, supports None values, and round-trips all fields correctly. (tests/payments/product_serialization_test.py, tests/payments/product_serialization_test.pyR1-R99)

Typing Improvements

• Added Optional import from typing to support optional enum fields in the model. (checkout_sdk/payments/payments.py, checkout_sdk/payments/payments.pyR5)
