Upgrade windows node image on GKE

[roberthbailey]

Is your feature request related to a problem? Please describe.
With Kubernetes 1.24, GKE will no longer be supporting node images with the dockershim runtime, which includes windows_ltsc (the image currently used in our windows instructions).

Describe the solution you'd like
We should switch to a node image with the containerd runtime, such as windows_ltsc_containerd or windows_sac_containerd .

Describe alternatives you've considered
We could instead drop our support for windows.

Additional context
I'm not sure if we need to change anything in our build scripts / instructions to support the updated node image.

According to this, since GKE version 1.23, it was no longer possible to either create new clusters that use Docker-based node images or add new node pools with Docker-based node images to an existing cluster. So our instructions and commands to create the Windows node pool was already incorrect since then.

I'm testing #2910 by following this to run the simple-game-server on windows node. But the game server pods keep failing health check. Then I tried to run the simple-game-server on a windows node (with WINDOWS_LTSC image) within a cluster with lower k8s version (1.22), it still failed the health check.

When you run through https://agones.dev/site/docs/guides/troubleshooting/ for the GameServer - what do you see?
