ZHA automatic network discovery of Zigbee coordinator bridges/gateways (Ethernet/WiFi network adapters) that support Zeroconf or SSDP?

FYI, for reference, noticed fairecasoimeme from ZiGate is working on PR for ZiGate discovery support:

https://github.com/home-assistant/core/pull/68577

PR will add ZHA automatic ZeroConf/MDNS discovery of ZiGate Ethernet Gateway (not WiFi Gateway).

PS: Other Home Assistant / ZHA developers started assisting fairecasoimeme once PR was submitted.
