Validator.derivedEnumeration to handle sealed sub-level traits

[ivan-klass]

Fix Validator.derivedEnumeration for cases like below

sealed trait EnumRoot
sealed trait ABranch extends EnumRoot
sealed trait BBranch extends EnumRoot

case object A1 extends ABranch
case object A2 extends ABranch

case object B1 extends BBranch

Validator.derivedEnumeration[EnumRoot]

Expected

• Validation one of (A1, A2, B1)

Actual

• compile error All children must be objects or enum cases

Thanks! I think we'd need similar changes in the scala-2 version of the macro?

Sure! Fixed. Also realized that scala-3/sttp/tapir/ValidatorScala3EnumTest.scala wasn't the right place for the test - moved to the shared part.
