Modify Kiali deployment commands and add Prometheus

[yuvraj9]

Description

Add Prometheus installation as a default step in the Istio Getting Started documentation. Kiali relies on Prometheus for metrics, so the dashboard does not work without it. This is especially important for kind clusters, where Prometheus must be installed explicitly.

Hi @yuvraj9. Thanks for your PR.

I'm waiting for a github.com 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.
