Automatic vscode detection is not always working

[hoxbro]

Continuation of #5007.

When running VSCode inside a virtualization/containerized environment, for example, WSL on Windows, the system environment variable we use VSCODE_PID to detect if we are running inside a vs code notebook is not set. Below is an example of the VSCODE_ environment variables set in a notebook environment on WSL.

Would propose we check for VSCODE_CWD in addition to VSCODE_PID
