[doc] Fix gethostbyname_ex description (GH-28700) (GH-28742)
It seems part of `gethostbyname_ex` doc was copied from `gethostbyaddr`. The latter has an `ip_address` parameter whereas the former doesn't.
(cherry picked from commit 4103280b83e1419bef535a42813d6dbe83bfe880)

- triple ``(hostname, aliaslist, ipaddrlist)`` where *hostname* is the primary
- host name responding to the given *ip_address*, *aliaslist* is a (possibly
+ triple ``(hostname, aliaslist, ipaddrlist)`` where *hostname* is the host's
+ primary host name, *aliaslist* is a (possibly
empty) list of alternative host names for the same address, and *ipaddrlist* is
a list of IPv4 addresses for the same interface on the same host (often but not
always a single address). :func:`gethostbyname_ex` does not support IPv6 name
