It looks like we can't really benefit from this rule because usually we
need to specify the option anyway (maybe `user has_many :comments` is
one of the few exceptions). We might make some changes in the code when
Rubocop changes its Rails/InverseOf rule so it doesn't report this case
when using Rails 7, but, until then, we aren't changing anything so we
don't have to deal with false positives in Rubocop.
