DeprecationWarnings with Python 3.12

[glatterf42]

With dask v2024.2.0, we are seeing another DeprecationWarning:

.venv/lib/python3.12/site-packages/pandera/typing/dask.py:9
  /home/fridolin/ixmp4/.venv/lib/python3.12/site-packages/pandera/typing/dask.py:9: DeprecationWarning: The current Dask DataFrame implementation is deprecated. 
  In a future release, Dask DataFrame will use new implementation that
  contains several improvements including a logical query planning.
  The user-facing DataFrame API will remain unchanged.
  
  The new implementation is already available and can be enabled by
  installing the dask-expr library:
  
      $ pip install dask-expr
  
  and turning the query planning option on:
  
      >>> import dask
      >>> dask.config.set({'dataframe.query-planning': True})
      >>> import dask.dataframe as dd
  
  API documentation for the new implementation is available at
  https://docs.dask.org/en/stable/dask-expr-api.html
  
  Any feedback can be reported on the Dask issue tracker
  https://github.com/dask/dask/issues 
  
    import dask.dataframe as dd

Curiously, we use dask.dataframe as dd here:

ixmp4/ixmp4/data/db/base.py

Lines 302 to 303 in 6f71751

	# https://github.com/dask/dask/issues/9710
	dd.from_pandas(df, chunksize=512_000) # type: ignore

But the error message doesn't point us there. Instead, it almost looks like it refers to pandera's usage of dask.dataframe again (though if the user-facing API remains the same, why bother?). Either way, the topic has been raised with dask and they are reworking the DeprecationWarning, it seems.
