### What changes were proposed in this pull request? 1, in PyArrow 13.0.0, the behavior of `Table#to_pandas` and `ChunkedArray#to_pandas` changed, set the `coerce_temporal_nanoseconds=True` according to [1](https://arrow.apache.org/docs/python/generated/pyarrow.Table.html#pyarrow.Table.to_pandas) and [2](https://arrow.apache.org/docs/python/generated/pyarrow.ChunkedArray.html#pyarrow.ChunkedArray.to_pandas) 2, there is another undocumented breaking change in data type conversion [`TimestampType#to_pandas_dtype`](https://arrow.apache.org/docs/python/generated/pyarrow.TimestampType.html#pyarrow.TimestampType.to_pandas_dtype): 12.0.1: ``` In [1]: import pyarrow as pa In [2]: pa.timestamp("us", tz=None).to_pandas_dtype() Out[2]: dtype('<M8[ns]') In [3]: pa.timestamp("ns", tz=None).to_pandas_dtype() Out[3]: dtype('<M8[ns]') In [4]: pa.timestamp("us", tz="UTC").to_pandas_dtype() Out[4]: datetime64[ns, UTC] In [5]: pa.timestamp("ns", tz="UTC").to_pandas_dtype() Out[5]: datetime64[ns, UTC] ``` 13.0.0: ``` In [1]: import pyarrow as pa In [2]: pa.timestamp("us", tz=None).to_pandas_dtype() Out[2]: dtype('<M8[us]') In [3]: pa.timestamp("ns", tz=None).to_pandas_dtype() Out[3]: dtype('<M8[ns]') In [4]: pa.timestamp("us", tz="UTC").to_pandas_dtype() Out[4]: datetime64[us, UTC] In [5]: pa.timestamp("ns", tz="UTC").to_pandas_dtype() Out[5]: datetime64[ns, UTC] ``` ### Why are the changes needed?
