We can't enable `Rails/WhereNot` lint/autofix, because it would break
code that uses mini_sql instead of AR (which rubocop, and tbh also we,
can't easily differentiate)
Those are safe because they either:
* are executed in AR model scope definitions
* are clearly chained starting from a AR model
* are less-clearly chained, but still can be traced to a AR model/scope
