[docs] update promql query for istio request duration

A minor issue I stumbled across while learning how to drive Flagger, is that the docs still use `istio_request_duration_seconds_bucket` to illustrate the query behind the `request-duration` metric. I understand that this changed with Istio 1.5 (fluxcd#478), but it seems that in the current version of flagger, the correct metric must already be used, since I'm getting duration metrics out of Istio 1.10 :) This change simply makes the docs clearer for those of us trying to understand exactly what `request-duration` entails!
