Schema description update should be considered as a metadata change

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

Reproduziere den bereitgestellten OpenAPI-Diff und untersuche anschließend core/src/main/java/org/openapitools/openapidiff/core/model/ChangedSchema.java im Bereich der referenzierten Zeile 160 sowie ChangedMetadata.java und die Metadatenbehandlung in ChangedSchema.java. Erledigt ist die Aufgabe, wenn eine Änderung, die ausschließlich die Beschreibung eines Schemas betrifft, als Metadatenänderung und nicht lediglich als abwärtskompatibel gemeldet wird.
