Minor clarifications and corrections throughout document.

Removed information about the content-length property from the Communicating with APNs chapter. This property is not relevant to the APNs provider API because of two factors. 1. An APNs payload always fits inside a single DATA frame. 2. The length of a DATA frame is declared in the frame header, according to the HTTP/2 specification. Eliminating the content-length property reduces bandwidth, complexity, and processing time for APNs requests.
