Not working/listening on IPv6

[DennisGlindhart]

Describe the bug
Connecting to the IPv6 address of the IP (both Pod, LoadBalancer etc.) doesn't work.
curl -v http://\[2001:db8::10::1\]:80

To Reproduce
Steps to reproduce the behavior:

1. Deploy nginx gateway fabric on IPv6-enabled (or IPv6-only cluster)
2. curl -v http://<IPv6Address>:80 to IP of the nginx pod, LB etc. (Or hostname/DNS-name

Expected behavior
Able to connect, like via IPv4

Your environment

• NGINX Gateway Fabric 1.2
• Kubernetes 1.29
• Nginx Gateway Fabric Pod exposed via LoadBalancer
• NGINX Configuration: kubectl -n nginx-gateway exec <gateway-pod> -c nginx -- nginx -T

Additional context
Expected fix:
All "listen <port>"-directives in internal/mode/static/nginx/config/servers_template.go should have a corresponding
listen [::]:<port>

Hey Dennis, sorry for the delay in response! We are aware that NGF does not support listening on IPv6 or sending to IPv6 addresses at this time, but we are planning on implementing it in 1.4.

I'll move this issue into the milestone so we can track that work here until the epic is more detailed.
