Support the NetApp Astra Trident CSI driver on aws-k8s variants

**What I'd like:**

Add the NetApp Astra Trident CSI driver to the choices for NFS persistent volumes in Bottlerocket on EKS, to permit those custommers to take full advantage of the FSx for ONTAP product from AWS.

**Any alternatives you've considered:**

Customers can use the kubernetes CSI driver today, and Bottlerocket does include the components needed to mount NFS file shares via the `mount` command. There is customer demand for the Trident driver, and EKS suggests using Trident.
