Delete leftover "respectively" from 6th paragraph of [JSON] Section 5, Service Document

The 6th paragraph in section 5, Service Document, used to read:

JSON objects representing a function or action import MUST contain this name/value pair with a value of FunctionImport or ActionImport, respectively.

However, action imports should never appear in the service document, so we (correctly) removed the reference to Action Imports. However, we accidentally left in the trailing ",respectively":

JSON objects representing a function import MUST contain the kind name/value pair with a value of FunctionImport, respectively.
