privateMetafieldNamespaces deprecated on graphql API

[rafaelmarques]

Hi everyone,

I'm trying to generate my local schema but now I'm getting an error 

Field "privateMetafieldNamespaces" is not defined by type "WebhookSubscriptionInput". Did you mean "metafieldNamespaces"?

I'm not sure if I should accept the error suggestion or this is really something I need to remove from the code.
