IPv6 exit node ACL not working

[fuomag9]

Bug description

Is ipv6 exit node with ACL possible? As the ACL below makes ipv4 work but ipv6 does not, and I see this in the logs, which does not seem correct:

Mar 21 20:41:49 headscale headscale[7944]: 2023-03-21T20:41:49+01:00 WRN No IPs found with the alias all6

On discord it was suggested to use [::]/0 but that did not work as well and outputted the same log

To Reproduce

Create an exit node and use the following ACL

{
  "groups": {
    "group:admin": ["fuomag9"]
  },
"Hosts": {
        "all6":  "::/0",
    },
  "acls": [
   { "action": "accept", "src": ["group:admin"], "dst": ["group:admin:*"] },
   {"action": "accept", "src": ["group:admin"], "dst": ["0.0.0.0/0:*"]},
   {"action": "accept", "src": ["group:admin"], "dst": ["all6:*"]}
  ]
}

It will be useful to reconsider this use case, now that the #1473 has passed.

"dst": ["::/0:*"],

works for me to enable IPv6
