Matt Palmer 4d3d6f8d3a Strip non-address characters from Forwarded for=
This is something of a followup to #2528, which asked for port information to not be included in  when it was taken from the local socket.

The  header's  element may optionally contain port information (https://datatracker.ietf.org/doc/html/rfc7239#section-6).
However, as I understand it,  is *supposed* to only contain an IP address, without port (per #2528).

This PR corrects that discrepancy, making it easier to parse the result of this method in application code.

There should not be any compatibility concerns, as anyone parsing the output of  would already need to handle both port and portless cases anyway.
