Hello everyone, could you tell me how to achieve the following structured config by using Pulumi GO sdk with Automation API:

config:
  myNamepace:myStorage:
    name: myStorageName
    size: 50

I have tried the following:

jsonString := `{"name": "test", "size": 100}`
err = stack.SetConfig(ctx, "myNamepace:myStorage", auto.ConfigValue{
        Value:  jsonString,
	    Secret: false,
})

I got the following result which is not what I want:

config:
  myNamepace:myStorage: '{"name": "test", "size": 100}'
