[red-knot] Fix diagnostic range for non-iterable unpacking assignments (#15994) 
## Summary

I noticed that the diagnostic range in specific unpacking assignments is
wrong. For this example

```py
a, b = 1
```

we previously got (see first commit):

```
error: lint:not-iterable
 --> /src/mdtest_snippet.py:1:1
  |
1 | a, b = 1
  | ^^^^ Object of type `Literal[1]` is not iterable
  |
```

and with this change, we get:

```
error: lint:not-iterable
 --> /src/mdtest_snippet.py:1:8
  |
1 | a, b = 1
  |        ^ Object of type `Literal[1]` is not iterable
  |
```

Markdown files within the mdtest/ subdirectory are tests of type inference and type checking; executed by the tests/mdtest.rs integration test.

See crates/red_knot_test/README.md for documentation of this test format.
