unneeded_override rule does not check init

Environment

In the following code, override init() will not trigger:

    }

    override func printHi() {
        super.printHi()
    }

I opened #5270 with a new option for the rule to affect initializers. I set the option to false by default but I don't know if it is the best decision. It is also my first PR here, so if anyone has suggestions please feel free.
