Description of the problem

Now that this has landed: mdn/content#38027 I think it would be a good opportunity to add the links for explicit resource management. To start with the fs module.

For example, FileHandle operations could reference MDN's await using documentation to show modern resource management patterns alongside traditional try/finally approaches.

And I guess that any other part that uses this could benefit from it too.

I will create a small PR for the fs module.
