Use default dependency keys for cuML

[bdice]

Use cuML’s default dependency keys instead of its custom devcontainers key now that conda-forge XGBoost no longer depends on RMM.

Merge and publish this feature before NVIDIA/cuml#8660.

Part of rapidsai/build-planning#312.

Failures look like they're in cuVS, something cutile-related. That shouldn't be a blocker for this change. Merging.

Thanks Bradley! 🙏

We are seeing the following error in CI:

Not creating 'rapids' conda environment because 'rapids.yml' is empty.

Is there something else we are missing from this change (or cuML)?

[bdice]

That isn't the true error. That 'rapids.yml' is empty. happens before repos are cloned and the environment is created. The failures are cuVS related, which I mentioned above. That is not a blocker for this to merge.

I think NVIDIA/cuml#8660 contains a fix for the cuTile issue, but it depended on this PR merging first.
