example dashboards use angular which is depreciated in grafana

[jcpunk]

What happened?

When importing the example dashboards from manifests/grafana-dashboardDefinitions.yaml into grafana 10.4 it reports angular integration is deprecated.

Did you expect to see some different?

No deprecated pannels

How to reproduce it (as minimally and precisely as possible):

Install grafana 10.4, import dashboards, view dashboards in web interface
