Build and test with CUDA 12.5.1

[KyleFromNVIDIA]

This PR updates the latest CUDA build/test version 12.2.2 to 12.5.1.

Contributes to rapidsai/build-planning#73

I think we should update this too, to encourage use of newer CUDA versions:

dask-cuda/docs/source/install.rst

Lines 15 to 19 in fe23e45

	To install the latest version of Dask-CUDA along with CUDA Toolkit 12.0:
	.. code-block:: bash
	conda install -c rapidsai -c conda-forge -c nvidia dask-cuda cuda-version=12.0

I've now seen a couple like that:

rapidsai/raft#2378 (review)

rapidsai/cuvs#219 (review)

None are technically "wrong", as they say "for CUDA 12.0...", but they all use only a single minor version (e.g. there's no "for CUDA 12.2...", "for CUDA 12.3...", etc.), so I think the intent is to be up to date with the latest minor version supported across RAPIDS.

It think it'd be worth adding rules like the following to the rapids-reviser migration.

For any .md or .rst file:

• replace CUDA 12.[0-9]+ with CUDA 12.{target_version}
• replace cuda-version=12.[0-9]+ with cuda-version=12.{target_version}
