ssh does not work when Hostname is an ipv6

[martinetd]

What Operating System(s) are you seeing this problem on?

Linux X11

WezTerm version

20240811-112922-0ac1e948 (built from source just now)

Describe the bug

With a ssh config such as

Host localtest
   Hostname ::1

the connection fails with:

Using libssh-rs to connect to user@::1:22
Error: Fatal: failed to set option

⚠️  Process RemoteSshDomain didn't exit cleanly
Exited with code 1.
This message is shown because exit_behavior="CloseOnCleanExit"

I'm not sure if it is relevant or if options are set individually, but the log message does not enclose the ipv6 with brackets e.g. user@[::1]:22 as it probably should.

(I guess that using libssh instead of spawning a ssh process is useful for cross-platform compatibility? so I'll spare you trying to preach just forking a ssh process instead)

Configuration

no config

Having the same issue on nightly:

wezterm chokes on the ipv6 hostname but ssh works fine.

This worked fine on stable (Feb 3rd, 2024) release.
