Update version of Grafana and statsd-exporter used for --integration statsd (#57855)

The version of these in Breeze was quite out of date -- we updated the version
in the chart in mid 2025 (with Helm 1.16). Crucially the statsd exporter
update allows us to use dogstatsd style tags to be automatically turned in to
Prometheus label metrics.
