passt.1: Fix typo, improve wording in examples of port forwarding specifiers

Browse Source 
Based on a patch from Laine, and reports from Laine and Yalan: fix
the "22-80:32-90" example, and improve wording for the other ones:
instead of using "to" to denote the end of a range, use "between ...
and", so that it's clear we're *not* referring to target ports.

IPv6 bound ports are also forwarded for IPv4.
