Summary
Restores the "Container discovery" section that was accidentally dropped in #18998 when swarm networking content was deduplicated from
network/drivers/overlay.mdintoengine/swarm/networking.md.The removed content documented that
tasks.<service-name>DNS lookups return individual task IP addresses for a service — a useful swarm-specific feature for service-to-service discovery without going through the VIP.The new section is placed directly after the VIP/DNSRR service discovery descriptions, within the "Configure service discovery" section, which is the right location for this content.
Issue
Fixes #24940
