Multilabel Classification FutureWarning with KNeighborsClassifier.predict()

In the Multilabel Classification section, the following code generates a warning:

```python
knn_clf.predict([some_digit])
```

The warning is:

```
[c:\tools\Anaconda3\lib\site-packages\sklearn\neighbors\_classification.py:228](file:///C:/tools/Anaconda3/lib/site-packages/sklearn/neighbors/_classification.py:228): FutureWarning: Unlike other reduction functions (e.g. `skew`, `kurtosis`), the default behavior of `mode` typically preserves the axis it acts along. In SciPy 1.11.0, this behavior will change: the default value of `keepdims` will become False, the `axis` over which the statistic is taken will be eliminated, and the value None will no longer be accepted. Set `keepdims` to True or False to avoid this warning.
mode, _ = stats.mode(_y[neigh_ind, k], axis=1)
```

I verified I have the latest repo code.
