ValueError: "Unknown label type: 'unknown'" when class column has Pandas type like Int64

### Describe the bug

I use Pandas to load data from CSV and transform it.
Pandas often parses integer columns as float, so I usually use `df = df.convert_dtypes()` to bring those columsn back to int.
It looks like this causes Pandas to make all integer columns `Int64`.

When I try to train some Scikit-Learn models like `LogisticRegression` on such data I get error `ValueError: Unknown label type: 'unknown'`. 

I think there was some effort to prevent this issue, I see it. https://github.com/scikit-learn/scikit-learn/blame/bb080aa690364d84d11232c73dc8db2f0dde3578/sklearn/utils/validation.py#L796


### Steps/Code to Reproduce

```
import sklearn
import pandas

df = pandas.DataFrame({"class": [0, 1, 0, 1, 1], "feature_1": [0.1, 0.2, 0.3, 0.4, 0.5]})
df = df.convert_dtypes()
model = sklearn.linear_model.LogisticRegression()
model.fit(
    X=df.drop(columns="class"),
    y=df["class"],
)
```

### Expected Results

I expect the model to be trained.

### Actual Results
