EKS Version is not updated

[leiicamundi]

Looking at, it seems that we don't update the EKS version like we do in https://github.com/camunda/camunda-tf-eks-module/blob/a73848e9dd2653cb431c51b740b73a93ef5ef88c/modules/eks-cluster/variables.tf#L16

c8-multi-region/aws/dual-region/terraform/variables.tf

Line 38 in 78b0ec1

default = "1.30"

I'm referencing this issue for later implementation
