 Container resources can now specify an `ImagePullPolicy` to control when the image is pulled. This is useful for resources that are updated frequently or that have a large image size. The following policies are supported:
 
-- `Default`: Default behavior (which is the same as missing in 9.2).
+- `Default`: Default behavior (which is the same as `Missing` in 9.2).
 - `Always`: Always pull the image.
 - `Missing`: Ensures the image is always pulled when the container starts.
