CalibratedClassifierCV doesn't work with `set_config(transform_output="pandas")`
### Describe the bug

CalibratedClassifierCV with isotonic regression doesn't work when we previously set `set_config(transform_output="pandas")`.
The IsotonicRegression seems to return a dataframe, which is a problem for `_CalibratedClassifier`  in `predict_proba` where it tries to put the dataframe in a numpy array row `proba[:, class_idx] = calibrator.predict(this_pred)`.

### Steps/Code to Reproduce

```python
import numpy as np
from sklearn import set_config
from sklearn.calibration import CalibratedClassifierCV
from sklearn.linear_model import SGDClassifier

set_config(transform_output="pandas")
model = CalibratedClassifierCV(SGDClassifier(), method='isotonic')
model.fit(np.arange(90).reshape(30, -1), np.arange(30) % 2)
model.predict(np.arange(90).reshape(30, -1))
```

### Expected Results

It should not crash.

### Actual Results
