DOC: CI failure due to fsspec deprecation warning

[ShaharNaveh]

There is CI failure in the Web/Docs, under check ipython directive errors on github actions, noticed on #32831 and on #32830

The error that is being shown:

Run ! grep -B1 "^<<<-------------------------------------------------------------------------$" sphinx.log
  FutureWarning,
<<<-------------------------------------------------------------------------
##[error]Process completed with exit code 1.

---

The root cause of the problem, is a warning that is generated during the creation of the docs.

Thanks @jorisvandenbossche I have updated the post above :)

@TomAugspurger @martindurant is this something to report to dask?

The warning comes from this snippet in the pandas docs:

   import dask.dataframe as dd
   ddf = dd.read_parquet("data/timeseries/ts*.parquet", engine="pyarrow")
   ddf

which gives the warning:

FutureWarning: The default value of auto_mkdir=True has been deprecated and will be changed to auto_mkdir=False by default in a future release.

This is with fsspec 0.6.3?

dask/dask#6028 is the same apparently.
