Check the available versions for the clusters within the Azure Portal
Read the linked documentation for the Kubernetes upgrade and recommendations for upgrading.

Upgrade default value for k8s_version in modules/consortium_cluster/variables.tf
Overwrite k8s_version in variables.tf (int-cluster) or main.tf (stable-cluster) of the clusters, in case you cannot upgrade the instance.
Perform terraform plan to validate the changes to kubernetes version of our AKS resources
Run terraform apply to upgrade our resources to the new kubernetes version if the plan is valid
