Challenge: cuda-core needs to depend on either cuda-bindings v11 or 12, but we don't generate the v11 variant in the main branch. We'll need to cache the artifacts from both main and 11.8.x branches so that all pipelines can use them (#329).

Turns out the build failure is due to race condition that the upload-artifact did not address with overwrite: true... (search for the 409 error here)

FYI I pushed a commit 6bb7c0b to allow passing through [all] to cuda-bindings. It's being backported in #391.
