Hyperpod EKS cfn stack reference issue

Hi team,

Encountering an issue when trying to launch an hyperpod eks cluster with the automated shell script. It was a due to a cfn reference issue here:

We have references to `PrivateRouteTable`, but the instance itself is named PrivateRouteTable1.
I was able to fix it by renaming this line to `PrivateRouteTable1`or renaming all references to `PrivateRouteTable1` to `PrivateRouteTable`.
