Fix pyarrow FileInfo import

[jrbourbeau]

Custom serialization for pyarrow.fs.FileInfo was recently added to help with Parquet in Dask DataFrame (xref #9025) but this import isn't quite right

In [1]: import pyarrow

In [2]: pyarrow.fs.FileInfo
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[2], line 1
----> 1 pyarrow.fs.FileInfo

AttributeError: module 'pyarrow' has no attribute 'fs'

I think this went unnoticed because in the Dask DataFrame case we trigger this correct import first

https://github.com/dask/dask/blob/c8ef947bd38e2b739ad3eccdbcce42e08d8c3f4a/dask/dataframe/dask_expr/io/parquet.py#L21

first which allows the import here to work.

However in the non-Dask DataFrame parquet case, that correct import doesn't happen and folks hit the AttributeError
