import openapi no request-validation info

[cortex35]

Issue description

Hello,

I try to use this exemple :
https://apisix.apache.org/docs/dashboard/2.8/IMPORT_OPENAPI_USER_GUIDE/#configure-a-route-with-parameters-validation

I put this yaml in a file and import it with apisix-dashboard ( Menu Route -> Advanced -> import ).

The result does not add request-validation plugin with info, is this functionnality is deprecated or abandonned ?

Thanks

Expected behavior

Route add contain request-validation plugin
Exemple :

uri: /hello
name: hello
methods:
  - POST
plugins:
  request-validation:
    body_schema:
      properties:
        name:
          type: string
        status:
          type: string
      rejected_msg: customize reject message
      required:
        - status
      type: object
