[Bug] Kafka Exporter dashabord does not work in newer Grafana versions

[scholzj]

The Kafka Exporter Grafana dashboard which we provide as part of our examples does not seem to work in newer Grafana versions such as 9.x or even 8.x. Check the attached screenshots => weird decimal numbers seem to be listed in places where they make no sense (e.g. number of topics or partitions) and the tables seem to be broken.

Note: All seems to work fine on older Grafana versions such as 7.x.
