debugger: Special-case npm et al. as program field for JS debug definitions (#32549)

Send `runtimeExecutable` and `runtimeArgs` instead of `program` and
`args` to avoid the DAP implicitly wrapping the command in `node`.

This means that putting `pnpm vitest <file>` as the command in the
launch modal will work, as will this in debug.json:

```
[
  {
    "adapter": "JavaScript",
    "type": "pwa-node",
    "label": "Label",
    "request": "launch",
    "program": "pnpm",
    "args": ["vitest", "<file>"],
    "cwd": "/Users/name/project"
  }
]
```


Release Notes:

- Debugger Beta: made it possible to use commands like `pnpm
<subcommand> <args>` in the launch modal and debug.json
