[BUG]: Installing morpheus-core requires specifying the rapidsai channel

[dagardner-nv]

Version

24.10

Which installation method(s) does this occur on?

Conda

Describe the bug.

Not all users will know that adding -c rapidsai is needed, we should investigate if there is something we can add to our package to look in the rapidsai channel for our deps.

Running :

create -n package-test -c nvidia morpheus-core

Yields an error:

Channels:
 - nvidia
 - conda-forge
Platform: linux-64
Collecting package metadata (repodata.json): done
Solving environment: failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - nothing provides cudf needed by morpheus-core-24.10.00-cuda_12.5_py3.10_g4c30f89b_0

Could not solve for environment specs
The following package could not be installed
└─ morpheus-core is not installable because it requires
   └─ cudf, which does not exist (perhaps a missing channel).

Minimum reproducible example

create -n package-test -c nvidia morpheus-core

It's possible to use dependency-specific channel prefixes, like rapidsai::morpheus-core instead of just morpheus-core, but this could lead to broken solves if for some reason we start publishing to multiple channels if down-stream dependencies specify different prefixes. That seems unlikely, and we could always go back to non-prefixed dependencies in the future.
