Game servers are having some delays until getting external IPs from agones SDK

[ytkang]

What happened:
Hi, recently I tried to update agones version from 1.38.0 to 1.42.0
But I found one issue,
Normally my game server gets external ip address from the gameServer, err := sdk.GameServer() object.
In 1.38.0 version, this gameServer object had this IP address in gameServer.Status.Address array right after I got the gameServer object.
But In 1.42.0 version, gameServer.Status.Address doesn't have any addresses and has empty array at the moment server is up, so I should poll this information by calling sdk.GameServer() with some interval. after a few mintues, it finally got the address array.

What you expected to happen:
IP address should be exists in gameServer.Status.Address array right after the sdk initialized

How to reproduce it (as minimally and precisely as possible):

• setup agones 1.41.0 or 1.42.0
• try to get gameServer.Status.Address right after the game server pod is up

Anything else we need to know?:

Environment:

• Agones version: 1.42.0
• Kubernetes version (use kubectl version): 1.28
• Cloud provider or hardware configuration: AWS EKS
• Install method (yaml/helm): helm
• Troubleshooting guide log(s):
• Others:

Here are the Game server pod and agones game server yamls
Before I got IP address
