Schema description update should be considered as a metadata change

Reproduza o diff de OpenAPI fornecido e, em seguida, inspecione core/src/main/java/org/openapitools/openapidiff/core/model/ChangedSchema.java próximo à linha 160 referenciada, juntamente com ChangedMetadata.java e o tratamento de metadados em ChangedSchema.java. A tarefa estará concluída quando uma alteração somente na descrição de um schema for reportada como uma alteração de metadados, em vez de ser apenas considerada compatível com versões anteriores.

Hello,

When diffing this spec:

openapi: 3.0.3
info:
  title: Test
paths:
  /foo:
    post:
      requestBody:
        content:
          application/json:
            schema:
              type: string
              description: desc v1

with this one:

openapi: 3.0.3
info:
  title: Test
paths:
  /foo:
    post:
      requestBody:
        content:
          application/json:
            schema:
              type: string
              description: desc v2

I get the following output:

==========================================================================
==                            API CHANGE LOG                            ==
==========================================================================
                                   Test                                   
--------------------------------------------------------------------------
--                            What's Changed                            --
--------------------------------------------------------------------------
- POST   /foo
  Request:
        - Changed application/json
          Schema: Backward compatible
--------------------------------------------------------------------------
--                                Result                                --
--------------------------------------------------------------------------
                   API changes are backward compatible                    
--------------------------------------------------------------------------

Since only the description field changed, I would expect a "metadata" change instead of a "compatible" one.

Changes to the description are correctly marked as metadata ones internally (see here and here) but I suspect the final value that is picked up to be the default one returned here. I don't have the time or means to debug it further however.

Tested version: 2.1.0-beta.11
