rubocop --auto-gen-conf exits with 1

[Ana06]

When rubocop find offenses it exits with 1, which in general is expected. But when running rubocop --auto-gen-conf I would expect that it returns 1 only if something went wrong and 0 in other case, as that there are offenses is expected and doesn't mean that the execution of the command went wrong. 😕

@Ana06 @bbatsov I would like to contribute solving this issue, but I think returning 0 when there are offenses will cause many tests to fail, so should I can those tests to always expect 0 when --auto-gen-conf option is present?

[Ana06]

@MagedMilad nice that you want to work on that! 💘 I think --auto-gen-conf should return 0 when the todo file is successfully created, without taking into account if there are offenses and the tests should also be changed to follow this.

@Ana06 @bbatsov just made a Pull request #6165, But I can't assign a reviewer to it, also I'm not sure this is the right way to handle auto-gen-config because it's my first time contributing in rubocop
so any comment on the PR will be very appreciated
