[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 | ``` ## Test Plan New snapshot tests.
