New description:

 Depends on disabling descriptor publication on reachability
 failures in #33223.

 Should be done after the first IPv6 address guessing feature: #33238
 or #33240.

 If both reachability checks succeed, relays should publish their IPv4 and
 IPv6 ORPorts in their descriptor.

 If only the IPv4 ORPort check succeeds, and the IPv6 address was guessed
 (rather than being explicitly configured), then relays should:
   * publish their IPv4 ORPort in their descriptor,
   * stop publishing their IPv6 ORPort in their descriptor, and
   * log a notice about the failed IPv6 ORPort reachability check.

 See proposal 312, section 3.2.7, Guessed IPv6 Reachability Failure part:
 https://gitweb.torproject.org/torspec.git/tree/proposals/312-relay-auto-
 ipv6-addr.txt#n567
