False positive WPS122 when using _ in a for loop

[ramast]

Bug report

What's wrong

    for _ in range(10):
        print('hello')

test.py:1:1: WPS122 Found all unused variables definition: _

How it should be

Using _ inside for loop is actually recommended by WPS123 so it shouldn't be an error.
