`dask cuda` CLI doesn't work with click 8.0.x

[jacobtomlinson]

I just ran into an issue with running dask cuda worker if you have click 8.0.x.

$ conda create -n dask-cuda-click -y -c conda-forge python=3.10

$ conda activate dask-cuda-click

$ pip install dask[complete] dask-cuda==23.10.0 click==8.0.4

$ dask cuda worker
/home/jtomlinson/miniconda3/envs/dask-cuda-click/lib/python3.10/site-packages/dask/cli.py:100: UserWarning: While registering the command with name 'cuda', an exception ocurred; 'function' object has no attribute 'command'.
  warnings.warn(
Usage: dask [OPTIONS] COMMAND [ARGS]...
Try 'dask -h' for help.

Error: No such command 'cuda'.

$ python -c "import dask_cuda.cli"
Traceback (most recent call last):

It looks like we indirectly depend on click via dask, so I've opened https://github.com/dask/dask/pull/10623 to propose bumping the minimum to click>=8.1 there.

Do we also want to add that dependency here and set a similar minimum?
