Extra values in triage work item value is breaking api spec work item creation

Create a workitem failed to create an API Spec work item with exception:

> The field 'APISpecDefinitionType' contains the value 'TypeSpec + DPG' that is not in the list of supported values".

When the `API SPEC` work item is created, the logic looks at the `Triage` workitem values. It copies the value for management or data plane.

The problem here is that the field `Triage Data API Spec Definition Type` uses more values that are not part of the `APISpecDefinitionType`.

**Action** is to clean up all triage issues and eliminate values that are not `OpenAPI` or `Typespec`. The list of issues is: https://dev.azure.com/azure-sdk/Release/_queries?tempQueryId=f4309599-0351-468c-a676-5588093a9e75
