passt.1: Fix typo, improve wording in examples of port forwarding specifiers
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. Reported-by: Laine Stump <laine@redhat.com> Reported-by: Yalan Zhang <yalzhang@redhat.com> Fixes: da20f57f19dc ("passt, qrap: Add man pages") Signed-off-by: Stefano Brivio <sbrivio@redhat.com>

IPv6 bound ports are also forwarded for IPv4.
