fix: change color validation functionality in isValidHsl.ts

The 'isValidHsl' function has been updated. It's no longer validating 'undefined' as 'deg' unit and no longer returning 'NaN' for default cases. Additionally, the check for 'h' not being 'NaN' has been removed. Values are now correctly validated within their respective ranges.
