Redundant modality modifier

Reports the modality modifiers that match the default modality of an element (final for most elements, open for members with an override).

Example:

  final class Foo

  open class Bar : Comparable<Bar> {
      open override fun compareTo(other: Bar): Int = 0
  }

After the quick-fix is applied:

  class Foo

  open class Bar : Comparable<Bar> {
      override fun compareTo(other: Bar): Int = 0
  }
