[improvement] Add directions for instrumenting a mixed Windows/Linux Kubernetes cluster

[maxlemieux]

• What problems does this PR solve?
  We don't document Kubernetes integration installation for a mixed cluster today.

• Add any context that will help us review your changes such as testing notes,
  links to related docs, screenshots, etc.

This recipe has been tested on mixed clusters on AKS and is drawn from a combination of two public docs:

Preview Windows installation (Only describes newrelic-infrastructure v2 installation, does not address anything else in the bundle): https://docs.newrelic.com/docs/kubernetes-pixie/kubernetes-integration/installation/kubernetes-integration-install-configure/#windows-install

Helm installation (Only addresses the bundle on Linux, does not address Windows): https://docs.newrelic.com/docs/kubernetes-pixie/kubernetes-integration/installation/kubernetes-integration-install-configure/#man-helm

Thanks for all the improvements. I fixed '2002' to '2022' with that last commit.
