Releasing v1.20.1

Added some addition from long time Pull Request, But one of the most important one comes from the recent addition by @WilliamDeBruin on PR #484 . The benefit from that is, as mentioned in the PR:

✅ Enable direct field access on interface{} types in rules
✅ Maintain backward compatibility with existing functionality
✅ Simplify rule writing for complex data structures
✅ Natural rule syntax that's intuitive for developers
