Dashboards don't match metric attributes

It looks like the dashboards in this repo do not match the exported metrics.

For instance - the grafana query:
```
histogram_quantile(0.5, sum(rate(controller_runtime_reconcile_time_seconds_bucket{app="confluent-operator",
confluent_platform=~"true",kubernetes_namespace=~"$namespace", kubernetes_pod_name=~"$pod_name"}[5m])) by (le, controller))
```
uses metric `controller_runtime_reconcile_time_seconds_bucket`

while metric attributes differ from query:
```
controller_runtime_reconcile_time_seconds_bucket{controller="confluentrolebinding", endpoint="http-metric", instance="172.16.107.115:7778", job="confluent-operator", le="+Inf", namespace="confluent", pod="confluent-operator-55695f4b58-c42r7", service="confluent-operator"}
```
Is it possible to get these dashboards to work with current set of exported metrics?

Start by comparing the Grafana query for controller_runtime_reconcile_time_seconds_bucket with the exported metric sample in the issue, focusing on label names and values. Review the repository's dashboard definitions and current metric source, then verify that the affected dashboards query the exported labels and display data successfully.
