Use cupy 12.2.0 as oldest dependency pinning on CUDA 12 ARM (#16808)

Uses cupy 12.2.0 as oldest dependency pinning on ARM to ensure CUDA 12 support.

This will fix nightly CI failures that look like:

```
LibMambaUnsatisfiableError: Encountered problems while solving:
  - package cupy-12.0.0-py311h308989c_2 requires python_abi 3.11.* *_cp311, but none of the providers can be installed

Could not solve for environment specs
The following packages are incompatible
├─ cuda-version 12.2**  is installable and it requires
│  └─ cudatoolkit 12.2|12.2.* , which can be installed;
├─ cupy 12.0.0  is installable with the potential options
│  ├─ cupy 12.0.0 would require
│  │  └─ cudatoolkit >=11.2,<12 , which conflicts with any installable versions previously reported;
...
```
