BUG: Buffer dtype mismatch on Windows and NumPy 2.0

### Describe the bug

Recent [Azure CI failure for MNE-Python](https://dev.azure.com/mne-tools/mne-python/_build/results?buildId=27722&view=logs&jobId=dded70eb-633c-5c42-e995-a7f8d1f99d91&j=dded70eb-633c-5c42-e995-a7f8d1f99d91&t=02d70add-cf2e-52ae-1ea0-298f1e5f37ea) shows a NumPy 2.0 incompatibility with sklearn, both installed via 
```
	python -m pip install --only-binary ":all:" --extra-index-url "https://pypi.anaconda.org/scientific-python-nightly-wheels/simple" "numpy>=2.0.0.dev0" "scipy>=1.12.0.dev0" scikit-learn matplotlib
```

### Steps/Code to Reproduce

Not on Windows at the moment so can't make a MWE (can if it's not obvious from the traceback!) but this is what's failing on CIs:
```
pytest mne/decoding/tests/test_search_light.py -k test_search_light
```

### Expected Results

No error

### Actual Results

### Versions

```shell
Can't run as it's on CI, but these are the reported versions:

├☑ numpy                2.0.0.dev0+git20231102.439762c (OpenBLAS 0.3.23.dev with 2 threads)
├☑ sklearn              1.4.dev0
```

COMMENT:
I assume that it was what @seberg was solving in https://github.com/scikit-learn/scikit-learn/pull/27041
