Fix: Support for sorting simple arrays (integers/strings) with SortArray (Fixes #4929)

- Added methods `byValueAscending()` and `byValueDescending()` to the SortArray class
  to support sorting simple array types (e.g., integers, strings) in ascending and descending order.
- Updated tests to verify the correct functionality of sorting arrays by value.
- Refactored SortArray to handle sorting of simple types without requiring a property for sorting.
