Issue Description

I have the following example Kubernetes manifest:

      containers:
          image: registry1.azurecr.io/repository1:latest

I have configured this DevOps task to update the container image:

      - task: KubernetesManifest@0
        inputs:
          action: deploy
          containers: |
            registry2.azurecr.io/repository2:${{parameters.version}}
          manifests: |
            $(System.DefaultWorkingDirectory)/manifest.yaml

Expected: The container image is updated to registry2.azurecr.io/repository2:${{parameters.version}}.

Actual: The container image is not updated. No warnings or errors logged.

I've found the code which is responsible, it's here: https://github.com/microsoft/azure-pipelines-tasks/blob/v232/Tasks/KubernetesManifestV1/src/utils/KubernetesObjectUtility.ts#L339-L363

See that it will only update the image if the registry/repository match. I don't know what the reasoning is (we assume it's because the manifests/containers are both lists and could not be in-order), but if it's expected, please update the containers part of the task documentation to say this.

This took several hours to figure out why the container image was not updating.

I also spent a bit of time debugging this "issue". The check seems to make sense so just having something in the docs would be appreciated.
