Prevent killing VS Code tasks after reloading VS Code

I generally using tasks for simplifying development process.
But some reasons I need to reload the VS Code (extension update, freezing etc.) and running task are gone.
Thanks to highlighted line we can prevent this:

.vscode/tasks.json

{
  "tasks": [
    {
      "detail": "vitepress dev docs",
      "isBackground": true,
      "label": "dev",
      "problemMatcher": [],
      "script": "docs:dev",
      "type": "npm"
    }
  ],
  "version": "2.0.0"
}
