Describe the bug, including details regarding any error messages, version, and platform.

In [1]: import pyarrow as pa

In [4]: pa.array(pa.array([float("nan"), None]), from_pandas=True)
Out[4]: 
<pyarrow.lib.DoubleArray object at 0x7f91bbd90f40>
[
  nan,
  null
]

In [5]: pa.__version__
Out[5]: '14.0.1'

If an arrow array is considered an ndarray-like data according to the docs, I would assume the nan would be inferred as null
