please add examples for adding windows worker node

[alnhk]

Hello.,

With help of this EKS terraform examples, we were able to provision the large scale DEV, STAGING and PRODUCTION AWS EKS environment, however, please add the examples on adding windows worker node to existing AWS EKS clusters.

Like, using "eks-worker" along with nodegroup configured for linux ,we are able to provision linux based worker, however for windows, did googled everywhere, it has "eks-worker-windows" or "eks_worker_windows" configured along with custom nodegroup for windows support., needs nodegroup for windows as well as eks worker windows related examples so that best practice can be followed.

This is appreciated.
