BUG: select_dtypes does not work with timestamp[ns][pyarrow]

[dbalabka]

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

import pandas as pd
import pyarrow

# Create a sample DataFrame
data = {
    'id': [1, 2, 3],
    'date1': pd.to_datetime(['2023-01-01', '2023-01-02', '2023-01-03']),
    'date2': pd.to_datetime(['2023-02-01', '2023-02-02', '2023-02-03']),
    'value': [10, 20, 30]
}

df = pd.DataFrame(data)

# Convert datetime columns to 'timestamp[ns][pyarrow]'
df = df.astype({
    'date1': 'timestamp[ns][pyarrow]',
    'date2': 'timestamp[ns][pyarrow]',
    'value': 'int64[pyarrow]'
})

print('\n\nAll types:\n' + str(df.dtypes))
print('\n\nIt works for other types `int64`:\n' + str(df.select_dtypes(include=['int64']).dtypes))
print('\n\nIt works for other types `pd.ArrowDtype(pa.int64())`:\n' + str(df.select_dtypes(include=[pd.ArrowDtype(pa.int64())]).dtypes))
print('\n\nBut it does not for `timestamp[ns][pyarrow]`:\n'  + str(df.select_dtypes(include=['timestamp[ns][pyarrow]']).dtypes))
print('\n\nThe type should not interpreter as `datetime64[ns]`:\n'  + str(df.select_dtypes(include=['datetime64[ns]']).dtypes))
print('\n\nHere is a proper workaround with `pd.ArrowDtype(pa.timestamp(ns))`:\n'  + str(df.select_dtypes(include=[pd.ArrowDtype(pa.timestamp('ns'))]).dtypes))

All types:
id                        int64
date1    timestamp[ns][pyarrow]
date2    timestamp[ns][pyarrow]
value            int64[pyarrow]
dtype: object

It works for other types `int64`:
id                int64
value    int64[pyarrow]
dtype: object

It works for other types `pd.ArrowDtype(pa.int64())`:
id                int64
value    int64[pyarrow]
dtype: object

But it does not for `timestamp[ns][pyarrow]`:
Series([], dtype: object)

The type should not interpreter as `datetime64[ns]`:
date1    timestamp[ns][pyarrow]
date2    timestamp[ns][pyarrow]
dtype: object

Here is a proper workaround with `pd.ArrowDtype(pa.timestamp(ns))`:
date1    timestamp[ns][pyarrow]
date2    timestamp[ns][pyarrow]
dtype: object

Issue Description

For unknown reasons, select_dtypes can not select the timestamp[ns][pyarrow] type because of the incorrect string-representation to type object conversion. It does work when we use type object explicitly like: pd.ArrowDtype(pa.timestamp('ns'))

Expected Behavior

select_dtypes should select columns with timestamp[ns][pyarrow] type when timestamp[ns][pyarrow] string provided.
select_dtypes should select columns with timestamp[ns][pyarrow] type when pd.ArrowDtype(pa.timestamp(ns)) object provided.
select_dtypes should not select columns with timestamp[ns][pyarrow] when datetime64[ns] provided.

Related to the following line:

pandas/pandas/core/frame.py

Line 4895 in 2cdb97e

dtype = dtype if not isinstance(dtype, ArrowDtype) else dtype.numpy_dtype

The following line should not return the timestamp[ns][pyarrow] types:

df.select_dtypes(include=['datetime64[ns]'])

Here is a proper workaround: avoid using string representation of the type and provide object type explicitly:

df.select_dtypes(include=[pd.ArrowDtype(pa.timestamp('ns'))])

[dbalabka]

it looks related to #52577

[yuanx749]

Seems it does not work with other pyarrow string representation either:

print(df.select_dtypes(include=['int64[pyarrow]']).dtypes)
# Series([], dtype: object)
