fix e2e: add missing plugin-name input to plugin-e2e workflow

The rook plugin E2E workflow was calling the reusable plugin-e2e workflow
without the required plugin-name input. This caused the ConfigMap naming
and mount path to fall back to the headlamp-kube-vip defaults, breaking
E2E runs for the rook plugin.

Fix: pass plugin-name: rook to the reusable workflow.
