fileTransformationsUtility should read EnvironmentName from Environment.Name instead of Release.Stage #532
Description
The fileTransformationsUtility used by IISWebAppDeploymentOnMachineGroup@0 can be used in a modern yaml based pipeline which does not set the classic Release.Stage variable to anything. It sets Environment.Name instead. This lib should be updated to support both variables.
