edit name of ingress gateway install

[tesla59]

Description

This PR updated release name of the istio gateway installed using helm. While in the gateway docs the release name is istio-ingressgateway, in the helm installation doc for istio the release name is istio-ingress.

Due to this change, anyone following the helm installation doc will have gateway label as istio: gateway instead of istio: ingressgateway. Other installation method sets the labels as istio: ingressgateway and the other docs also assume the label to be istio: ingressgateway.

• We care about quality, so we've put in place a number of checks to ensure our documentation

  To publish them sooner, add a cherrypick/release-x.xx label, where x.xx is the current
  release of Istio.

Hi @tesla59. Thanks for your PR.

I'm waiting for a istio member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

users should understand what fields link things up and set them to match when appropriate.

While i agree that the user should be aware of how the selector is working, i think we should mention it in docs then. if installing using istioctl sets istio: ingressgateway, other installation method should at least mention it. We are doing it at one place but not doing at other. we should make it clear in the doc itself that the istio: ingressgateway is just a label selector and it can even be foo: bar
