Remove UCX-Py

[pentschev]

UCX-Py is deprecated and being archived. This change removes all UCX-Py tests, leaving only UCXX tests, and all mentions in favor of UCXX. See rapidsai/ucx-py#1160 for details.

I searched like this:

git grep -E 'ucx\-py|ucp'

Found just one more use.

This old example (using Corey's fork of ucx-py 😅) should probably be updated / removed:

cuml/wiki/mnmg/Using_Infiniband_for_MNMG.md

Line 36 in feea7fe

git clone https://github.com/cjnolet/ucx-py.git

Marking this "approve", so you all can do whatever you want with that and not need another review from me.

I'll leave this up to cuML folks, the example hasn't been updated since 2023 apparently, and is still pointing to CUDA 9.2! I think it's safe to say this is not being actively used.

I am not sure whether the example is still relevant in its current form. However, unless we can verify that the instructions still work work with ucxx, we should just mark them as deprecated by adding a deprecation notice at the top of the page.

Added a deprecation notice in 6e1b508 .
