On this page: https://docs.redhat.com/en/documentation/red_hat_openshift_service_mesh/3.2/html/installing/ossm-istio-ambient-mode#ossm-about-istio-ambient-mode_ossm-istio-ambient-mode

Search for "Ambient mode remains a Technology Preview feature." and remove this sentence, as that is no longer the case.

The rest of the sentence is not completely correct either:

While well-defined discovery selectors allow a service mesh deployed in ambient mode alongside a mesh in sidecar mode, this scenario has not been thoroughly validated. To avoid potential conflicts, install Istio ambient mode only on clusters that do not have an existing Red Hat OpenShift Service Mesh installation. Ambient mode remains a Technology Preview feature.

as this will be covered by: https://issues.redhat.com/browse/OSSM-11008

Once we have incorporated OSSM-11008, this paragraph should be removed.
