fix: remove Category inheritance from ArrowDictionary

[darenliang]

This PR removes Category inheritance from ArrowDictionary because it does not need the category attribute check here: https://github.com/unionai-oss/pandera/blob/main/pandera/dtypes.py#L483

Old behavior:

import pyarrow
from pandera.engines.pandas_engine import ArrowDictionary

int64_dictionary = ArrowDictionary(value_type=pyarrow.int64())
string_dictionary = ArrowDictionary(value_type=pyarrow.string())

int64_dictionary.check(string_dictionary)  # True

New behavior:

int64_dictionary.check(string_dictionary)  # False
