[BUG] [scala-pekko] Array of enums fails to generate valid code

Description

https://github.com/OpenAPITools/openapi-generator/commit/72e942f81b2636ce69bfe32018de0ccb26bb1bd3 fix was applied for sttp generator. Same problem still occures with scala-pekko.

Tried with all the recent versions and 3.0.4, same issue occures

OpenAPI declaration file content or url

type: object
required:
  - id
properties:
  id:
    type: string
    format: uuid
  categoryKey:
    type: string
  templateKey:
    type: string
  stateFilters:
    type: array
    items:
      type: string
      enum:
        - state_new
        - state_pending
        - state_approved
        - state_rejected
        - state_archived

This generates invalid class where with typing

case class ConditionalActionGenericForIssue (
  id: UUID,
  categoryKey: Option[String] = None,
  templateKey: Option[String] = None,
  stateFilters: Option[ConditionalActionGenericForIssueEnums.Seq[StateFilters]] = None
) extends ApiModel

object ConditionalActionGenericForIssueEnums {

  type Seq[StateFilters] = Seq[StateFilters].Value

  object Seq[StateFilters] extends Enumeration {
  }

}

Start with the scala-pekko generator and compare its array-of-enums handling with the referenced sttp fix. Reproduce the issue using the YAML declaration in the report; done when the generated Scala code is valid and represents stateFilters as an array of enum values.
