Wrong or Misleading documentation about `strictBuiltinIteratorReturn`

[ac10n]

In TSConfig - Strict - strictBuiltinIteratorReturn, the documentation says:

Built-in iterators are instantiated with a TReturn type of undefined instead of any.

Maybe it should be:

-Built-in iterators are instantiated with a `TReturn` type of undefined instead of `any`.
+Built-in iterators are instantiated with a `TReturn` type or undefined instead of `any`. 

or even:

-Built-in iterators are instantiated with a `TReturn` type of undefined instead of `any`.
+Built-in iterators are instantiated with a `TReturn | undefined` type instead of `any`. 

Also, an example can be useful.

I do not believe either change is correct. See: https://devblogs.microsoft.com/typescript/announcing-typescript-5-6/#strict-builtin-iterator-checks-(and---strictbuiltiniteratorreturn)
