[TS] Still open, regression in handling enums

[andreaTP]

Look like #4199 has been closed too early, I'm trying with the 1.13 preview version of kiota and the latest published dependencies.
This spec:

openapi: 3.0.3
info:
  title: Apicurio Registry API [v3]
  version: 3.0.x
  description: Apicurio Registry.
  license:
    name: Apache 2.0
    url: https://www.apache.org/licenses/LICENSE-2.0
paths:
  "/admin/rules":
    get:
      responses:
        '200':
          content:
            application/json:
              schema:
                "$ref": "#/components/schemas/RuleType"
          description: The list of names of the globally configured rules.
      description: 'List global rules'
components:
  schemas:
    RuleType:
      description: ''
      enum:
      - VALIDITY
      - COMPATIBILITY
      - INTEGRITY
      type: string
      example: VALIDITY

produces code that doesn't compile:

export const RulesRequestBuilderRequestsMetadata: RequestsMetadata = {
    get: {
        uriTemplate: RulesRequestBuilderUriTemplate,
        responseBodyContentType: "application/json",
        adapterMethodName: "sendEnum",
        enumObject: RuleType,
    },
};

intuitively, the correct encoding should be enumObject: RuleTypeObject, but I haven't fully checked it.
