fix: sort redfish_exporter_targets to avoid config changes

When templating `redfish_exporter_targets` in `60-redfish.yml` the
groups are written randomly and as a result can cause unnecessary
updates to the templated file which can lead to reboots of prometheus
as well as polluting configuration diff.
