A Common-Sense Guide to AI Engineering: (B1.0) usage of non-existing return value from function in code example (page 117)

In the listing of the `rag()` function on page 116, no value is returned. But when that method is invoked in the code listing on page 117, a return value is expected and is assigned to the `documentation` variable:
```

documentation = rag(user_input, rag_chunks)

```

The initialization of the `documentation` variable should probably just be removed, as that variable is not used anywhere in the program.
