Merge branch 'rubocop/enable-negatedif-style-cop' into 'master'

Enable Style/NegatedIf Rubocop cop

Favor `unless` over `if` for negative conditions (or control flow ||).

```ruby
# bad
do_something if !some_condition
# bad
do_something if not some_condition

# good
do_something unless some_condition
# good
some_condition || do_something
```

See #17478
