nfs-monitor: fix node_exporter textfile_collector Helm chart key
Use extraHostVolumeMounts (prometheus-node-exporter sub-chart key for
host path mounts) instead of extraVolumes/extraVolumeMounts, which are
for general volumes. This correctly wires /var/lib/node_exporter/
textfile_collector into the container so the textfile arg takes effect.
