Remote SSH: `Hostname` instead of `HostName` fails with `getaddrinfo ENOTFOUND` in Match cases

Describe the issue:

I cannot use non-trivial SSH alias entries in "Connect to Host".

The "Remote Host" menu correctly identifies my ~/.ssh/config file, and it opens it and I can edit it if needed. I have an entry that looks like:

# this alias works
Host goodalias
  ForwardAgent yes
  User r2evans
  Hostname 111.222.33.44
  Port 2222

# this alias does not work
Host badalias
  ForwardAgent yes
  User r2evans
  # change the hostname based on current network
  Match originalhost badalias exec "ipconfig getsummary en0 | sed -nE 's/.* SSID : //gp' | grep -q 'MyClientWifi'"
      Hostname 11.22.33.44
      Port 22
  Match originalhost badalias
      Hostname 111.222.33.44
      Port 2222

The first goodalias works fine, the second badalias does not.

Steps to reproduce the issue:

1. Define an alias in ~/.ssh/config that points to a "real" hostname/ipaddr using Match originalhost (or perhaps other non-trivial conditioning).
2. Confirm that goodalias works in "Connect to Host...". (Disconnect.)
3. Try to use badalias, it fails with Error: getaddrinfo ENOTFOUND badalias

Expected or desired behavior:

if ssh badalias works in a terminal, I hope for it to work in Positron as well.

Were there any error messages in the UI, Output panel, or Developer Tools console?

In the "Output" pane:

(BTW, typo: attemp -> attempt)

Start with the Remote SSH authority-resolution path that emits the reported getaddrinfo ENOTFOUND badalias error; no source file or test is named in the issue. Reproduce using the provided ~/.ssh/config entries and compare Positron's resolution with ssh badalias in a terminal. Done means aliases using Match originalhost resolve and connect through Positron as they do in SSH.
