[BUG] CI job names are hard to understand

[jameslamb]

Describe the bug

Look at some of the status checks from #768

It's not clear at all from the check names that those are actually "the 4 CUDA 12.0.1, arm64 builds". Namely:

• ubuntu22.04 is mentioned twice (with 2 slightly different spellings)
• both amd64 and arm64 are in the job name

The second half of the name (not visible unless you mouse over it) is clearer:

docker / {first-par} / build (arm64, 12.0.1, ubuntu22.04, 3.12, 25.08)

We should make it easier to differentiate between jobs from the GitHub UI, by changing those names.

Steps/Code to reproduce bug

Look at any PR's CI check section.

Additional context

This could probably be done by just setting a short name in the name: field here:

docker/.github/workflows/build-test-publish-images.yml

Line 143 in cd18405

build-rapids:

and here:

docker/.github/workflows/build-test-publish-images.yml

Line 172 in cd18405

build-cuvs:

That should prevent that auto-generated first name with all the matrix elements mixed together from being used.
