Bisecting Kmeans fails to bisect a certain cluster

### Describe the bug

Hi all,

I'm using the `sklearn.cluster.BisectingKMeans` to perform a clustering, and it worked for a range of k values, until it failed at k=9 (I don't think the k-value is important though). The issue seems to be that it failed to split a cluster into 2, but got 2 identical centers instead. More details are given below.

### Steps/Code to Reproduce

I'm afraid I can't provide a minimal reproducible example without relying on external data. I've uploaded the training data to an empty repo: https://github.com/Xunius/dummy_repo

The only python script in the repo has only a few lines, but I'm assuming the `npz` data file is at the same folder as the `py` script. The code to reproduce the bug is:

```py
import numpy as np
from sklearn.cluster import BisectingKMeans

npz = np.load('./bisectkmeans.npz')

km = BisectingKMeans(n_clusters=9, init='random', max_iter=400,
                     n_init=10, random_state=10,
                     bisecting_strategy='largest_cluster')
X = npz['data']
weights = npz['weights']
km.fit(X, None, sample_weight=weights)
```



### Expected Results

No error is thrown

### Actual Results

Below is the Traceback info:

```
Traceback (most recent call last):
  File "bisectkmeans.py", line 12, in <module>
    km.fit(X, None, sample_weight=weights)
  File "/home/guangzhi/.local/mambaforge/envs/cdat/lib/python3.8/site-packages/sklearn/cluster/_bisect_k_means.py", line 411, in fit
    self._bisect(X, x_squared_norms, sample_weight, cluster_to_bisect)
  File "/home/guangzhi/.local/mambaforge/envs/cdat/lib/python3.8/site-packages/sklearn/cluster/_bisect_k_means.py", line 342, in _bisect
    cluster_to_bisect.split(best_labels, best_centers, scores)
  File "/home/guangzhi/.local/mambaforge/envs/cdat/lib/python3.8/site-packages/sklearn/cluster/_bisect_k_means.py", line 45, in split
    indices=self.indices[labels == 1], center=centers[1], score=scores[1]
IndexError: index 1 is out of bounds for axis 0 with size 1
```

Printing `np.unique(labels)` gives:

```
array([0], dtype=int32)
```
so the `labels` array is a length-6843 1d array with all 0s.

The `centers` array is a 2x7 array, with 2 identical rows:

```
(Pdb) centers
array([[-1.04880691,  1.47209268,  0.92988155,  1.16810444,  0.98679651,
        -1.4344821 , -0.70694216],
       [-1.04880691,  1.47209268,  0.92988155,  1.16810444,  0.98679651,
        -1.4344821 , -0.70694216]])
```

Going up 1 level in the stack and at Line 342 (`cluster_to_bisect.split(best_labels, best_centers, scores)`), it is noticed that the `best_inertia` variable is a tiny value: 

```
(Pdb) best_inertia
5.7262640016675594e-30
```
and the array `X` is a (6843, 7)` 2d array, with identical rows:

```
(Pdb) np.ptp(X,axis=0)
array([0., 0., 0., 0., 0., 0., 0.])
```

I'm not sure what's causing this failure, just in case it helps, I'm using some sample weights, and when it failed, I have some quite small weights:

```
(Pdb) sample_weight.shape
(6843,)
(Pdb) sample_weight.min()
1.1269358725791912e-09
(Pdb) sample_weight.max()
1.418544396650835e-05
(Pdb) sample_weight.sum()
0.03364984267143782
```

COMMENT:
Setting `OMP_NUM_THREADS=1` gets rid of the issue at the expense of performance, maybe an acceptable work-around until we fix this?
