Ill wait on work from @anthonykim1 here to implement since nushell compatibility might need some work

Hi @eleanorjboyd !

Will it be enough to have something like that (based on other scripts in this folder)?

debugpy.nu:

#!/usr/bin/env nu
# Nushell script

$env.DEBUGPY_ADAPTER_ENDPOINTS = $env.VSCODE_DEBUGPY_ADAPTER_ENDPOINTS
let python_cmd = if $nu.os-info.name == "windows" {
    "python"
} else {
    "python3"
}
^$python_cmd $env.BUNDLED_DEBUGPY_PATH --listen 0 --wait-for-client ...$nu.args

How can I easily test it in VSCode? Should I configure debugger to fetch this nushell script to have it working smoothly with Python Debugger?
