CSV: set maintainers to RH support, maturity stable

[jotak]

It's simpler if we just set a global RH support maintainer in the CSV description, rather than an individual list. Most other operators do that.
Also, set maturity as "stable" upstream (it was only done for downstream)

📝 Walkthrough

Walkthrough

The PR consolidates ClusterServiceVersion maintainer metadata from multiple individual contacts to a single Red Hat Support entry, marks the operator as stable rather than alpha, and updates the CSV build script to avoid overriding the maturity field that now comes from the base configuration.

Changes

ClusterServiceVersion Metadata Update

Layer / File(s)	Summary
CSV metadata consolidation config/csv/bases/netobserv-operator.clusterserviceversion.yaml, bundle/manifests/netobserv-operator.clusterserviceversion.yaml	Maintainers list replaced with single "Red Hat Support" entry (support@redhat.com); maturity field changed from alpha to stable in both base and bundle manifest.
Patch script alignment hack/patch_csv.py	Script no longer explicitly sets maturity to stable (now sourced from base config) and adds displayName assignment for "Network Observability".
