TypeError when fitting GridSearchCV or RandomizedSearchCV with OrdinalEncoder and OneHotEncoder in parameters grid

### Describe the bug

Having both `OrdinalEncoder` and `OneHotEncoder` inside the parameters grid to be used by the `GridSearchCV` or `RandomizedSearchCV` results in the following error: `TypeError: float() argument must be a string or a real number, not 'OneHotEncoder'`.

### Steps/Code to Reproduce

```python
import numpy as np
import pandas as pd
from sklearn import set_config
from sklearn.compose import ColumnTransformer
from sklearn.ensemble import HistGradientBoostingRegressor
from sklearn.model_selection import GridSearchCV, RandomizedSearchCV
from sklearn.pipeline import Pipeline
from sklearn.preprocessing import OneHotEncoder, OrdinalEncoder

set_config(transform_output="pandas")

# Setting seed for reproducibility
np.random.seed(42)

# Create a DataFrame with 1000 rows and 5 columns
num_rows = 1000
data = {
    "numeric_1": np.random.randn(num_rows),  # Normally distributed random numbers
    "numeric_3": np.random.randint(
        1, 100, size=num_rows
    ),  # Random integers between 1 and 100
    "object_1": np.random.choice(
        ["A", "B", "C", "D"], size=num_rows
    ),  # Random choice among 'A', 'B', 'C', 'D'
    "object_2": np.random.choice(
        ["X", "Y", "Z"], size=num_rows
    ),  # Random choice among 'X', 'Y', 'Z'
    "target": np.random.rand(num_rows)
    * 100,  # Uniformly distributed random numbers [0, 100)
}

df = pd.DataFrame(data)

X = df.drop("target", axis=1)
y = df["target"]

enc = ColumnTransformer(
    [("enc", OneHotEncoder(sparse_output=False), ["object_1", "object_2"])],
    remainder="passthrough",
    verbose_feature_names_out=False,
)

pipe = Pipeline(
    [
        ("enc", enc),
        ("regressor", HistGradientBoostingRegressor()),
    ]
)

grid_params = {
    "enc__enc": [
        OneHotEncoder(sparse_output=False),
        OrdinalEncoder(),
    ]
}

grid_search = GridSearchCV(pipe, grid_params, cv=5)
grid_search.fit(X, y)
# RandomizedSearchCV produces the same error
# rand_search = RandomizedSearchCV(pipe, grid_params, cv=5)
# rand_search.fit(X, y)
```

### Expected Results
I would have expected the pipeline to run without errors, like that:

COMMENT:
It's good to have a fix in scikit-learn, but I think the numpy behaviour is unexpected so I opened https://github.com/numpy/numpy/issues/26612.
