Consistent creation of zombie processes by vscode-eslint extension

[tategotoazarasi]

Environment:

• Operating System: Arch Linux
• VSCode Version: 1.89.1
• vscode-eslint Version: 2.4.4
• ESLint Version: 9.4.0

Issue Description: The vscode-eslint extension consistently leaves behind a zombie process specifically [npm config get ] <defunct> every time VSCode is closed. This issue occurs every time without exception, leading to additional wait times during system shutdown as the process is awaited to terminate.

Steps to Reproduce:

1. Open VSCode with the vscode-eslint extension enabled.
2. Close VSCode.
3. Check for zombie processes using ps -aux | grep defunct and observe the [npm config get ] <defunct> zombie process.

A zombie process [npm config get ] <defunct> remains each time VSCode is closed. The parent process typically is /opt/visual-studio-code/code /home/username/.vscode/extensions/dbaeumer.vscode-eslint-2.4.4/server/out/eslintServer.js --node-ipc --clientProcessId=94143

Killing the parent process results in the zombie being reattached to systemd, remaining as a defunct process. This causes significant delays during system shutdown due to the wait for this process to terminate.
