Enable ipv6 in coolify network

[Vahor]

Description

I need to access the ipv6 of an app running in a container.
But the network does not seem to be able to access those ips.

I can delete the coolify network and recreate it with ipv6 support but as it's also managed by coolify it seems hacky and doing so on every server does not seem nice.
(That's what I'm currently doing)

Doc is not very clear about what the flag does, but I also tried with --ip6, it does not change anything

Minimal Reproduction (if possible, example repository)

Inside a container using the coolify network
or docker run --rm -it --network coolify ubuntu

apt update && apt install curl -y
curl https://ipv6.icanhazip.com/

You'll see an error

curl: (7) Failed to connect to ipv6.icanhazip.com port 443 after 3 ms: Couldn't connect to server

(works for ipv4)

Note: or simpler by installing net-tools and running ifconfig, you'll see that with coolify network you don't have the inet6, but without the coolify network an address is here.

For comparison, you can run a container using the host network docker run --rm -it ubuntu. Same commands, here it woks.

#2495 can also be a solution, adding a custom network with ipv6 and using this one will solve my problem.
Edit: we'd still have to enable the ipv6 support on docker

Hey, we're running into this issue when trying to connect to a supabase DB which only support ipv6 for direct connections. @Vahor I'm looking into doing what you're doing, but I'm concerned I will recreate it with missing configuration. How did you recreate it exactly?

Would also love IPv6 support for Coolify networks. Same issue as @Jackman3005. I don't want to manually recreate a Coolify-managed resource, especially with no way to configure it in the UI itself
