feat(sync-actions): implement product tailoring actions and corresponding tests

- Added product tailoring functionality in `product-tailoring.ts` to handle various action groups including base, meta, images, assets, attributes, and variants.
- Created a comprehensive test suite in `product-tailoring-sync.spec.ts` to validate the behavior of the product tailoring actions, ensuring immutability and correctness of actions generated for various scenarios.
- Included edge case handling and support for staged actions based on publish and staged flags.
