PyPi release: every second job fails with an artifact conflict

[torymur]

Pypi release required 4 restarts of failed jobs to finish: https://github.com/dottxt-ai/outlines-core/actions/runs/13079996880

On each restart attempt any first job will succeed and after that any second job will fail with:

Error: Failed to CreateArtifact: Received non-retryable error: Failed request: (409) Conflict: an artifact with this name already exists on the workflow run

When we were using actions/upload-artifact and actions/upload-artifact of v3 we didn't have this issue, we had to upgrade to v4, since v3 was deprecated: #161

According to this: https://github.com/actions/upload-artifact/blob/main/docs/MIGRATION.md

Several behavioral differences exist between Artifact actions v3 and below vs v4

• In v3, Artifacts are mutable so it's possible to write workflow scenarios where multiple jobs upload to the same Artifact
• In v4, Artifacts are immutable (unless deleted).

And it also uploaded wheels only from the last job: https://pypi.org/project/outlines-core/0.2.2/#files
