Pandas version checks

  • I have checked that this issue has not already been reported.

  • I have confirmed this bug exists on the latest version of pandas.

  • I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

>>> df = pd.DataFrame({"A": pd.Series([1,2,3], dtype=pd.ArrowDtype(pa.int8())), "B": pd.Series([1,2,3], dtype=pd.ArrowDtype(pa.int16()))})
>>> df.describe(include=pd.ArrowDtype(pa.int8()))
         A    B
count  3.0  3.0
mean   2.0  2.0
std    1.0  1.0
min    1.0  1.0
25%    1.5  1.5
50%    2.0  2.0
75%    2.5  2.5
max    3.0  3.0
>>>

Issue Description

Only describe for column "A" should have been calculated, because it's the only int8 column in the dataframe.

Expected Behavior

Expected behavior is behavior with numpy types:

>>> df = pd.DataFrame({"A": pd.Series([1,2,3], dtype=np.dtype("int8")), "B": pd.Series([1,2,3], dtype=np.dtype("int16"))})
>>> df.describe(include=np.dtype("int8"))
         A
count  3.0
mean   2.0
std    1.0
min    1.0
25%    1.5
50%    2.0
75%    2.5
max    3.0
>>>

This only calculates describe for column "A".
