Add ARM environment & requirement files

[jakirkham]

As ARM becomes usage increases, it would be helpful for users to have easier paths to getting started. In particular it would be helpful to start creating conda environment and pip requirement files for ARM

This would involve creating a rapids-reviser patch that adds the following to dependencies.yaml and runs RDFG

     matrix:
       cuda: ["11.8", "12.5"]
-      arch: [x86_64]
+      arch: [aarch64, x86_64]

If there certain elements in the matrix that are missing a aarch64 resolution, then those elements may need to be added as well

The idea would be to roll this out across RAPIDS projects

Presumably you mean a rapids-reviser patch, otherwise yes this sounds good.

Yes a rapid-reviser patch that runs RDFG. Sorry 😂
