[BUG] Annotations have no effect on Option types

Scala version: 2.12.15

Describe the bug

Annotations have no effect on Option types.

How to reproduce?

  case class A(s: String)
  case class Input(
    @encodedExample(A("a").asJson)
    @default(A("a"), Some("a"))
    a: Option[A]
  )

It generates schema without default and example fields:

components:
  schemas:
    A:
      required:
      - s
      type: object
      properties:
        s:
          type: string

Additional information

It doesn't work for case classes but works for Option[String].
