[DOC] Document nvdashboard jupyterlab toggle accelerator for cudf.pandas

[ncclementi]

Documentation proposal

Since the jupyterlab-nvdashboard 0.15 release extension, if a user has cudf installed, the GPU toggle for cudf.pandas will be enabled. xref PR: rapidsai/jupyterlab-nvdashboard#248

This page https://docs.nvidia.com/cudf/26.08/cudf_pandas/usage/ should include documentation on how to use this feature.

For reference this is a short video explaining how it works. rapidsai/jupyterlab-nvdashboard#248 (comment)

We could limite this to a few screenshots, for simplicity since the video is long.

Suggested fix for documentation

I can make this contribution, I'd like a minimal guidance on the preferred way to contribute this.

Do you prefer screenshots, or a shorter video/gif ?

[mroeschke]

IMO I think a gif would be preferable over screenshots, but also since this component is maintained in jupyterlab-nvdashboard, could the gif and primary documentation live jupyterlab-nvdashboard and cudf's docs could cross reference to it?

@mroeschke this makes sense, that being said, the jupyterlab-nvdashboard extension doesn't have a docs page. The only existing docs are in the readme. We can modify the readme to make this more explicit and include gif and or screenshots there.
