Use original code blocs

[rgardler-msft]

When converting an existing doc the agent should, unless it finds an error, use the same code block as in the original document. Failure to do this can result in a passing test, but incomplete configuration.

For example, from the original doc I had:

az aks create \
--resource-group ${RG_NAME} \
--name ${AKS_NAME} \
--location ${LOCATION} \
--tier standard \
--kubernetes-version ${K8S_VERSION} \
--os-sku AzureLinux \
--nodepool-name systempool \
--node-count 3 \
--zones 1 2 3 \
--load-balancer-sku standard \
--network-plugin azure \
--network-plugin-mode overlay \
--network-dataplane cilium \
--network-policy cilium \
--ssh-access disabled \
--enable-managed-identity \
--enable-acns \
--generate-ssh-keys

The generated doc gave me:

az aks create \
  --resource-group $RESOURCE_GROUP_NAME \
  --name $CLUSTER_NAME \
  --node-count 1 \
  --generate-ssh-keys \
  --enable-managed-identity \
  --enable-aad \
  --disable-local-accounts \
  --kubernetes-version $AKS_VERSION  

This created a valid AKS cluster but subsequent commands didn't work.
