Invalid fix for PLE1141

[martinlehoux]

• I think the autofix is not safe
• Ruff version: 0.6.4
• Ruff command: ruff check --preview --fix

  
  d: dict[tuple[int, str], bool] = {}
  d[1, "a"] = True

for n, c in d: print(n, c)

autofixed to 

```py
d: dict[tuple[int, str], bool] = {}
d[1, "a"] = True

for n, c in d.items():
    print(n, c)

To summarize the issue:

• for n, c in d iterates over the dictionary keys
• for n, c in d.items() iterates over the key-value pairs.

It's questionable if PLE1141 should be raised for your example because the code only iterates over the keys. Pylint had a similar issue a long time ago https://github.com/pylint-dev/pylint/issues/3283

Yes exactly. But as I understand it, ruff doesn't use type checking, so it would be difficult to say that the key is a tuple.
