The PR add the `fix safety` section for rule `RUF007` (#15584 )

It seems that the fix was always marked as unsafe #14401

## Unsafety example

This first example is a little extreme. In fact, the class `Foo`
overrides the `__getitem__` method but in a very special, way. The
difference lies in the fact that `zip(letters, letters[1:])` call the
slice `letters[1:]` which is behaving weird in this case, while
`itertools.pairwise(letters)` call just `__getitem__(0), __getitem__(1),
...` and so on.

Note that the diagnostic is emitted: [playground](https://play.ruff.rs)

I don't know if we want to mention this problem, as there is a subtile
bug in the python implementation of `Foo` which make the rule unsafe.

```python
from dataclasses import dataclass
import itertools

@DataClass
class Foo:
    letters: str
    
    def __getitem__(self, index):
        return self.letters[index] + "_foo"


letters = Foo("ABCD")
zip_ = zip(letters, letters[1:])
for a, b in zip_:
    print(a, b) # A_foo B, B_foo C, C_foo D, D_foo _
    
pair = itertools.pairwise(letters)
for a, b in pair:
    print(a, b) # A_foo B_foo, B_foo C_foo, C_foo D_foo
```

This other example is much probable.
here, `itertools.pairwise` was shadowed by a costume function
[(playground)](https://play.ruff.rs)

```python
from dataclasses import dataclass
from itertools import pairwise

def pairwise(a):
    return []
    
letters = "ABCD"
zip_ = zip(letters, letters[1:])
print([(a, b) for a, b in zip_]) # [('A', 'B'), ('B', 'C'), ('C', 'D')]

pair = pairwise(letters)
print(pair) # []
