Local docker regression: REALTIME_IP_VERSION is ignored

Bug report

Describe the bug

Running a self-hosted instance on a server with ipv6 disabled is not working.

According the doc, setting the environment variable REALTIME_IP_VERSION to the value ipv4 should make the server bind to ipv4 only, but we still get the error:

  num_acceptors: 100,                                                                                     
  max_connections: 1000,                                                                                  
  socket_opts: [

    {:port,                                                                                                                                                                                                          
     4000}                                                                                                                                                                                                           
  ]                                                                                                       
}) for reason :eafnosupport (address family not supported by protocol family)     

This looks like a regression as this was supposed to be fixed: #253

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Disable ipv6 on your server
2. Add the environment variable REALTIME_IP_VERSION in the docker compose
3. run docker compose up -d
4. Check the logs docker logs realtime-dev.supabase-realtime

Expected behavior

Container realtime-dev.supabase-realtime crashes

System information

• OS: RHEL9

@jbertozzi I think supabase/supabase#13816 gives some clarity. Honestly, they just REALLY don't care about the open source/self-hosting side of things. We could fork of course... But honestly, they just simply don't care.

Thanks for flagging, I'll take a look.
