Enum collection properties are represented as strings

Taking a look at part of the metadata for the microsoft.graph.conditionalAccessConditionSet type

microsoft.graph.conditionalAccessConditionSet:
      title: conditionalAccessConditionSet
      required:
        - '@odata.type'
      type: object
      properties:
        servicePrincipalRiskLevels:
          type: array
          items:
            $ref: '#/components/schemas/microsoft.graph.riskLevel'
          description: 'Service principal risk levels included in the policy. Possible values are: low, medium, high, none, unknownFutureValue.'
        signInRiskLevels:
          type: array
          items:
            $ref: '#/components/schemas/microsoft.graph.riskLevel'
          description: 'Sign-in risk levels included in the policy. Possible values are: low, medium, high, hidden, none, unknownFutureValue. Required.'
        userRiskLevels:
          type: array
          items:
            $ref: '#/components/schemas/microsoft.graph.riskLevel'
          description: 'User risk levels included in the policy. Possible values are: low, medium, high, hidden, none, unknownFutureValue. Required.'

The properties userRiskLevels , userRiskLevels and servicePrincipalRiskLevels are a collection of the microsoft.graph.riskLevel enum.

They are however generated as List as seen at the link below.

This looks to be caused by the function not looking up the type for Enums and defaulting to string when the schema is a collection type.

if (string.IsNullOrEmpty(type?.Name))
