Python debugger doesn't allow env property

[llamafilm]

Type: Bug

I'm trying to add environment variables to a Python debugger using the below launch.json. It shows an error under env that "Property env is not allowed." The documentation here says env is allowed.

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python: Attach Local",
      "type": "debugpy",
      "request": "attach",
      "connect": {
        "port": 5678,
        "host": "localhost"
      },
      "justMyCode": false,
      "env": {
        "PYTEST_ADDOPTS": "--no-cov"
      },
      "pathMappings": [
        {
          "localRoot": "${workspaceFolder}",
          "remoteRoot": "."
        }
      ]
    }
  ]
}

That's correct error, as attach doesn't support this property because it connects to already running process and can't change that. Env would work on launch config.

This config is provided by extension anyway (see https://github.com/microsoft/vscode-python/blob/main/package.json#L910), but there is no bug or missing feature.
