"${command:pickRemoteProcess}" does not work with remote SSH security banner

Type: Debugger

Describe the bug

• OS and Version: Windows 10 Pro (64-bit) 10.0.19041
• Remote OS version: Ubuntu 16.04.7 LTS
• VS Code Version: Code 1.50.0
• C/C++ Extension Version: 1.0.1
• Other extensions you installed (and if the issue persists after disabling them): -

${command:pickRemoteProcess} does not work with a remote SSH server that displays a security banner before login.

To Reproduce

1. Set the banner in /etc/ssh/sshd_config:

Banner /some/path/sshd-banner

/some/path/sshd-banner:

========================== Authorized Access Notice ===========================
              This computer system is the property of Big Tech Co.
      Activities are actively monitored and unauthorized access or use of
                      this computer system is prohibited
===============================================================================

2. Create a launch configuration with "request": "attach", pipeTransport and "processId": "${command:pickRemoteProcess}"
3. Launch the configuration

Reproduce the issue with the /etc/ssh/sshd_config Banner setting and a launch configuration using pipeTransport and "processId": "${command:pickRemoteProcess}". Start by tracing how the remote process picker handles SSH output before login. Done means the picker works when the remote SSH server displays the documented security banner.
