Fix doctest bug in bubble_sort_recursive - incorrect function call (#13821)

Fixed bug in bubble_sort_recursive docstring where the doctest was calling bubble_sort_iterative([]) instead of bubble_sort_recursive([]). This was a copy-paste error that would cause the doctest to pass even if bubble_sort_recursive had issues with empty lists.

Change:
- Line 71: Changed '>>> bubble_sort_iterative([])' to '>>> bubble_sort_recursive([])'

This ensures the doctest properly validates the recursive implementation.
