Add honorLabels to pushgateway ServiceMonitor example in the Docs

[hille721]

Description

Without honorLabels: true the labels of the scraped metrics from the Pushgateway will have a exported_ prefix.

With that the query in the docs (absent(apiserver_audit_event_total{job="kube-scheduler"})) would still not work as it would be absent(apiserver_audit_event_total{exported_job="kube-scheduler"}).

With honorLabels: true, everything works as expected and also other queries are working in the same way as they are on other distributions without isolated CP.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update

How Has This Been Tested?

• Manual test
• Auto test added
