Description

I wanted to use different folders for saving my api and model documentation to. I saw that this was implemented here https://github.com/OpenAPITools/openapi-generator/pull/15561/files. When I include config below the template files still get saved in the same directory as before.

templateDir: ./sdk-resources/resources
packageName: Package
packageVersion: 1.2.3
apiVersion: v3
companyName: Company Name
packageGuid: a14925fb-44fb-447d-8708-6fbdf2762efa
commonVerbs: Delete=Remove:Cancel=Suspend:Patch=Update:List=Get:Query=Search:Run=Start:Validate=Confirm:Make=Select
discardReadOnly: true
templateOutputDirs:
  api_doc.mustache: ./methods
  model_doc.mustache: ./models

I would expect all api documentation to be in a root folder methods and model documentation to be in a root folder models

Suggest a fix

Start with sdk-resources/v3-config.yaml and the CLI generation command using api-specs/v3.yaml and the powershell generator; compare the templateOutputDirs behavior with the implementation introduced in PR 15561. Done means API documentation is generated under methods and model documentation under models instead of the previous shared directory.
