{Event Grid} Fix TypeError when specifying numerical CLI arguments for certain topic types

[wiebeck]

Description
Commit acd4633 removed the manual casting to int for several cli arguments and fixed that in the argument definition by specifying type=int but forgot to do the same for other sets of arguments (system and partner topics).

My GitHub workflow contains a run step with the following command:

az eventgrid system-topic event-subscription create \
  --name blobeventgrid \
  --resource-group $RESOURCE_GROUP \
  --system-topic-name evto-connect-${{ env.ENVIRONMENT }} \
  --deadletter-endpoint "/subscriptions/$SUBSCRIPTION_ID/resourceGroups/$RESOURCE_GROUP/providers/Microsoft.Storage/storageAccounts/$STORAGEACCOUNTNAME/blobServices/default/containers/XXX" \
  --endpoint "/subscriptions/$SUBSCRIPTION_ID/resourceGroups/$RESOURCE_GROUP/providers/Microsoft.Web/sites/$FUNCTION/functions/XXX" \
  --endpoint-type azurefunction \
  --event-ttl 360 \
  --max-delivery-attempts 10 \
  --included-event-types "Microsoft.Storage.BlobCreated" \
  --subject-ends-with ".xml" \
  --labels "github-actions"

Until now this always worked as expected. GitHubs base image for workflows recently updated to Azure CLI v2.22.0 and since then I got:

TypeError: '<' not supported between instances of 'str' and 'int'

Testing Guide
Just enter any az eventgrid system-topic event-subscription create command while specifying one of max-delivery-attempts, max-events-per-batch, preferred-batch-size-in-kilobytes or event-ttl.
