Logs for Prometheus's node exporter permanently accumulates

(same issues i filed earlier, just for Prometheus's Node exporter)

I've got a log file at /var/log/prometheus/node-exporter.log and it has logs dating back to 2023-04. It's currently 2023-09-15, which suggests the logs aren't ever rotated or cleaned up. Maybe it should be rotated, as it is 204M for me.
