Avoid mixing wheels between publish jobs

[aditya-pandey-dev]

This PR fixes issue #215 where the non-aarch64 publish job was also uploading the aarch64 wheel from the same workflow run.
The reusable publish workflow was downloading all artifacts matching dist-*, so every publish job could see wheels from other build jobs.

I made the wheel and sdist artifact names in publish.yml include the build target and updated the publish jobs to download only their own artifact instead of dist-*.
I run the publish workflow on the fix/artifact-scope branch and it no longer mixes artifacts between jobs. I’ll add the GitHub Actions run link here . https://github.com/aditya-pandey-dev/github-actions-workflows/actions/runs/20006487200

I took a look through the changes and this makes sense to me.
Scoping the artifact names per publish job and downloading only the job-specific artifacts should avoid mixing wheels across runs.
CI is green as well.
