Nick Khyl 0d8d3831b9 net/dns: use the correct separator for multiple servers in the same NRPT rule on Windows
If an NRPT rule lists more than one server, those servers should be separated by a semicolon (";"),
rather than a semicolon followed by a space ("; "). Otherwise, Windows fails to parse the created
registry value, and DNS resolution may fail.

Fixes #19040
Updates #15404 (enabled MagicDNS IPv6 by default, adding a second server and triggering the issue)
