BUG: creating column with ArrowDtype using pyarrow extension type fails on 2.0.3

[jorisvandenbossche]

Creating a pandas DataFrame using ArrowDtype holding a pyarrow array with extension type fails using pandas 2.0.3:

In [1]: ext_arr = pa.array(pd.period_range("2012", periods=3))

In [2]: df = pa.table({'col': ext_arr}).to_pandas(types_mapper=pd.ArrowDtype)
---------------------------------------------------------------------------
NotImplementedError                       Traceback (most recent call last)
Cell In[2], line 1
----> 1 df = pa.table({'col': ext_arr}).to_pandas(types_mapper=pd.ArrowDtype)

This works on the main branch, although there are still some other issues such as the repr not working, see #54062
