Subject: [PATCH] Filter dd deprecation (#1312)

Dask CUDA must use the deprecated `dask.dataframe` API until https://github.com/rapidsai/dask-cuda/issues/1311 and https://github.com/rapidsai/cudf/issues/15027 are both closed. This means that we must explicitly filter the following deprecation warning to avoid nighlty CI failures:

```
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
```

This PR adds the (temporarily) necessary warning filter.
