REST API: Clarify arguments passed to rest route get & update callbacks.
Update doc block argument definitions to clarify that the REST API always passes an array to the `get_callback` and always passes an entity object to the `update_callback`. Props TimothyBlynJacobs, salzano. Fixes #44432. git-svn-id: https://develop.svn.wordpress.org/trunk@45810 602fd350-edb4-49c9-b593-d223f7449a82
