Subject: [PATCH] Add `LocalizedError` conformance to `ConnectError` (#327)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This improves how error messages are surfaced through `ConnectError`.

Before:
```
(lldb) po response.error?.localizedDescription
▿ Optional<String>
  - some : "The operation couldn’t be completed. (Connect.ConnectError error 1.)"
```

After:
```
(lldb) po response.error?.localizedDescription
▿ Optional<String>
  - some : "The Internet connection appears to be offline."
```
