Docs: "Try it yourself" example of d.ts declaration usage doesn't work.

"Try it yourself" example of d.ts declaration usage doesn't work.

https://www.typescriptlang.org/docs/handbook/declaration-files/templates/module-d-ts.html

I don't know how to fix it as I'm trying to learn but the docs aren't clear. It doesn't work for me, and the example running on the site doesn't either.

The example is to show how the .d.ts file works - if you click on ".d.ts" tab in the sidebar, you can see how it works.

If you'd like to add a type to the arr, that'd be a good PR to send
