Subject: [PATCH] Only run Auto Assign PR workflow if PR is not merged (#17888)

It appears that currently the `.github/workflows/auto-assign.yml` workflow runs on every PR commit even when an assignee has already been set (e.g. https://github.com/rapidsai/cudf/actions/runs/13062684572/job/36449057944) and on merge on the current branch (e.g. https://github.com/rapidsai/cudf/actions/runs/13072179599/job/36476031430).

I think in theory we would only want to run this workflow once upon PR opening (?), but I added a condition to run this workflow if a PR does not have an assignee (name). cc @Matt711
