NetworkPolicy note in the operator monitoring

[squakez]

We need to clarify this is missing and it's part of the admin post-installation procedures. For example in the operator metrics chapter: https://camel.apache.org/camel-k/next/observability/monitoring/operator.html#metrics

Hi, I'd like to work on this issue. Could a maintainer please assign it to me?

I plan to add a focused note to the operator monitoring documentation explaining that administrators should configure a NetworkPolicy as part of the post-installation procedure. I'll keep the change documentation-only and follow the existing Antora conventions.
