Issue Summary

Lemmy cannot bind to an ipv6 address. Attempts to do so cause the app to fail with:

thread 'main' panicked at 'Failed to load settings file: LemmyError { message: None, inner: "invalid IP address syntax" near 3:24, context: "SpanTrace" }', crates/utils/src/settings/mod.rs:18:33

Steps to Reproduce

1. Set any ipv6 address (for example, ::/0) as bind in config.hjson

frebib@Poseidon C:\s\social> grep bind lemmy.hjson
  bind: "::"

or

frebib@Poseidon C:\s\social> grep bind lemmy.hjson
  bind: "2a02:<snip>:9::15"

frebib@frebib-PC ~> curl -v 'http://[2a02:<snip>:9::15]:8536'

Works for me with both :: and a specific address. Try to drop the netmask

You're right, my mistake!
