Fixes the following:

import pandas as pd
import numpy as np

data = np.random.randn(100, 10)
df = pd.DataFrame(data, dtype="float64[pyarrow]")

df.corrwith(df)

NotImplementedError: <class 'pandas.core.arrays.arrow.array.ArrowExtensionArray'> does not support reshape as backed by a 1D pyarrow.ChunkedArray.
