Update doctests in wiggle_sort to match fixed implementation output

- Updated expected outputs for negative array doctests in `sorts/wiggle_sort.py`.
- The previous doctest expectations relied on the incorrect behavior caused by the index-0 negative lookup bug.
- Fixes pytest doctest mismatch failure in CI build job.
