Issue Description

Installed Version:

import pycaret
pycaret.__version__
3.4.0

As already described here: [BUG]: compare_models with fit_kwargs bug] #2537 it is not possible to properly pass fit_kwards to compare_models. See more details in #2537

Reproducible Example

from pycaret.datasets import get_data
data = get_data('hepatitis')

from pycaret.classification import *
s = setup(data, target = 'Class', session_id = 123)

compare_models(fit_kwargs = {'sample_weight' : {0 : 1, 1 : 2}}, errors = 'raise')

Expected Behavior

It should work seamlessly.

Actual Results

TypeError: _fit_one() got an unexpected keyword argument 'class_weight'

During handling of the above exception, another exception occurred:

RuntimeError                              Traceback (most recent call last)
[/usr/local/lib/python3.10/dist-packages/pycaret/internal/pycaret_experiment/supervised_experiment.py](https://localhost:8080/#) in compare_models(self, include, exclude, fold, round, cross_validation, sort, n_select, budget_time, turbo, errors, fit_kwargs, groups, experiment_custom_tags, probability_threshold, verbose, parallel, caller_params)
    811             except Exception as ex:
    812                 if errors == "raise":
--> 813                     raise RuntimeError(
    814                         f"create_model() failed for model {model}. {type(ex).__name__}: {ex}"
    815                     )

RuntimeError: create_model() failed for model lr. TypeError: _fit_one() got an unexpected keyword argument 'class_weight'

Having the same issue here. A temporary fix is to create the models manually:

from catboost import CatBoostClassifier
model = pc.create_model(CatBoostClassifier(class_weights=class_weight))
