Thanks for opening the issue, I can reproduce on main.

Interesting, I think I might be able to get in a PR for this in a few days.

Same is true for regular dict:

a_dict = {
    'key': 0
}

a_dict['key'] = a_dict['key'] + 1  # [consider-using-augmented-assign]

It seems like it also applies for lists:

kiwi = [1, 2]
kiwi[0] = kiwi[0] + 1  # [consider-using-augmented-assign]
