fix Loggable[T].logShow to mask option fields noted with @masked

[NarekDW]

Let's say we have such a case class

  @derive(loggable)
  final case class MaskedOptBaz(
      @masked maybeStr: Option[String],
      @masked maybeInt: Option[Int],
      @masked maybeBool: Option[Boolean],
      @masked maybeDouble: Option[Double],
      @masked maybeStr2: Option[String]
  )

When I call the function

Loggable[MaskedOptBaz].logShow(maybeMasked)

Expectation:

MaskedOptBaz{maybeStr=Some(***),maybeInt=Some(###),maybeBool=Some(****),maybeDouble=Some(###.###),maybeStr2=<none>}

Actual behaviour:

MaskedOptBaz{maybeStr=str,maybeInt=123,maybeBool=true,maybeDouble=100.001,maybeStr2=<none>}
