v2doc: fix naming of response-end-pkt

> Git Protocol version 2[1] defines 0002 as a Message Packet that indicates
> the end of a response for stateless connections.
> 
> Change the naming of the 0002 Packet to 'Response End' to match the
> parsing introduced in Wireshark's MR !1922 for consistency. A subsequent
> MR in Wireshark will address additional mismatches.
