Fix articles/machine-learning/how-to-deploy-kubernetes-extension.md

The command for az k8s-extension create shows the config setting for InferenceRouterHA=False when it should be inferenceRouterHA=False. This causes the azureml-fe-v2 deployment to attempt to deploy three replicas. In a scenario where the user has less than three nodes, the extension deployment will fail.
