hi there everyone, hopefully this is a simple question.... how do you prevent configuration settings (in YAML files) from appearing in the "Configuration" section on the project stack? we will have API keys/passwords/connection string etc in the YAML file that we essentially extract and place in a KeyVault using Pulumi, however, those values in YAML are plain text sothey end up in plain text in Pulumi's stack view. Is there a way to prevent them from being uploaded to Pulumi or is there a way to encrypt them in the YAML file?
