Issue Description

The number of folds is not shown correctly when passing an sktime ExpandingWindowSplitter to the fold parameter.

Reproducible Example

# !pip install pycaret==3.0.0rc3

import numpy as np
from pycaret.time_series import TSForecastingExperiment
from pycaret.datasets import get_data
from sktime.forecasting.model_selection import ExpandingWindowSplitter

y = get_data(114, folder="time_series/seasonal", verbose=False)
cv = ExpandingWindowSplitter(fh=np.arange(1, 13), initial_window=24, step_length=4)
exp = TSForecastingExperiment()
exp.setup(y, fh=12, fold=cv)

Expected Behavior

Expected: "Fold Number" should list the number of folds in the CV step, but it just lists the ExpandingWindowSplitter object

Actual results:
