When running ruff --select=B006 b006.py --fix on a function like this

def test(arg=[]):
    import os

the fix would be:

def test(arg=None):
    if arg is None:
        arg = []
    import os

I would like to see the fix move below the import like this:

def test(arg=None):
    import os
    if arg is None:
        arg = []

For my own enjoyment, I have already started implementing this here. Though, as this is the first time I have written any Rust, it could likely be improved upon 😅
