Adding a TypeContent case of `type_contents_order`

• Updated SwiftLint to the latest version
• I searched for existing GitHub issues

Currently the TypeContent of type_contents_order is:

enum TypeContent: String {
    case `case` = "case"
    case typeAlias = "type_alias"
    case associatedType = "associated_type"
    case subtype = "subtype"
    case typeProperty = "type_property"
    case instanceProperty = "instance_property"
    case ibOutlet = "ib_outlet"
    case ibInspectable = "ib_inspectable"
    case initializer = "initializer"
    case typeMethod = "type_method"
    case viewLifeCycleMethod = "view_life_cycle_method"
    case ibAction = "ib_action"
    case otherMethod = "other_method"
    case `subscript` = "subscript"
    case deinitializer = "deinitializer"
}

It distinguishes between ib_outlet and instance_property, ib_action and other_method.

Would it be nice to have ib_segue_action as a case?
