it is not necessarily ‘Comparable`.
This cop is unsafe because even if a value has `<` or `>` method,

That it is slow though. So autocorrection will apply generic `max` or `min`:
NOTE: It can be used if you want to present limit or threshold in Ruby 2.7+.
Enforces the use of `max` or `min` instead of comparison for greater or less.
