skip CUDA 11.4 conda-python-tests jobs

[jameslamb]

CUDA 11.4 is only tested in nightly CI (not on PRs) for this project.

This project doesn't support CUDA 11.4 (because the versions of PyTorch it is compatible with don't), so #89 turned off most of those CUDA 11.4 test jobs. That worked for wheels, but conda tests need to be turned off as well.

This skips nightly tests against CUDA 11.4.

Notes for Reviewers

How I tested this

Triggered a run of the nightly test job from this branch (by clicking "Run workflow" here), using the latest nightly packages:

• use workflow from: pull-request/91
• branch: branch-24.12
• date: 2024-12-06
• sha: 7ec8ace3cf7007dcca796e484f587af77d328e8f (from https://github.com/rapidsai/cugraph-gnn/commits/branch-24.12/)

One test job here failed with what looked like network errors (build link). Restarted it.

I agree, the failure looks like a network error. Also it's definitely unrelated to the changes in this PR, which had the desired effect of removing 11.4 from the matrix, so I'm approving as is.
