remove alpine from CITGM runs

I recommend we skip alpine from CITGM runs, because it does not have the IPv6 network.

Another option is to setup IPv6. Alpine runs in containers, maybe it's an easy change to the Dockerfile.

I had a look and I think we would need to configure ipv6 at the Docker daemon level: https://docs.docker.com/config/daemon/ipv6/#use-ipv6-for-the-default-bridge-network

It seems relatively important to me that we keep running CITGM on Alpine hosts because many people use it in production.

Agreed. Anecdotally, but I don't think I've encountered any node projects in production that does not use alpine (except for some that need specific native dependencies that are way easier with a debian distro). Might of course be extra skewed by debian being easier, thus leading to less bug reports etc.
