Can't debug containerized Python app in WSL without DockerDesktop

[Wadzio]

OS: Windows 10 (21H2 build: 19044.1706)
VSCode: 1.67.1
VSCode-docker: 1.22.0
WSL2 with distro: Ubuntu 20.4, kernel 5.10.16
Docker in Ubuntu distro: 20.10.12
No DockerDesktop installed on OS

Everything works perfectly when we have DockerDesktop installed on the OS (it was fixed in #2641)

When we do not have DockerDesktop, and we have Docker installed in Ubuntu distribution in WSL, then when we try to debug containerized Python app we get "Timed out waiting for launcher to connect"

At the moment the only solution I could find is to manually enter the IP bridge gateway in the debugAdapterHost

launch.json

{
  "name": "Docker: Python - General",
  "type": "docker",
  "request": "launch",
  "preLaunchTask": "docker-run: debug",
  "debugAdapterHost": "172.17.0.1", // docker inspect --format '{{(index .IPAM.Config 0).Gateway}}' 'bridge'
  "python": {
    "pathMappings": [
        {
           "localRoot": "${workspaceFolder}",
           "remoteRoot": "/app"
        }
    ],
    "projectType": "general"
  }
}

I think with a minor adjustment to #3522 we can fix this.

This has now been released in Docker extension version 1.23.0.
