### Issue Type?

Feature Request

### Module Name

avm/res/container-service/managed-cluster

### (Optional) Module Version

1.13.1

### Description

When redeploying a cluster having changed the value of agentPoolProfile.vmSize, I get the following error message:

`##[error]PropertyChangeNotAllowed: Preflight validation check for resource(s) for container service aks-cdk-dev-westeurope in resource group rg-cdk-aks-dev-westeurope failed. Message: Changing property "agentPoolProfile.vmSize" is not allowed in an api-version before "2026-01-02-preview".. Details:
`

Can we get this module bumped to the latest schema version to unlock this feature?
