Sort order logic when getting all the versions of an artifact

[jonsnowseven]

Hello.

I have a question regarding the SortOrder query parameter when getting the versions of an artifact.

Using an Apicurio Registry 3.0.6's docker image, I registered two versions of an Artifact (AVRO schemas) and then I queried them with the following:

• ?orderby=createdOn&order=asc

  {
    "count": 2,
    "versions": [
      {
        ...
        "createdOn": "2025-03-19T14:24:30Z",
        ...
      },
      {
        ...
        "createdOn": "2025-03-19T14:22:40Z",
        ...
      }
    ]
  }

• ?orderby=createdOn&order=desc

  {
    "count": 2,
    "versions": [
      {
        ...
        "createdOn": "2025-03-19T14:22:40Z",
        ...
      },
      {
        ...
        "createdOn": "2025-03-19T14:24:30Z",
        ...
      }
    ]
  }

  This logic for SortOrder is not the usual in ordering parameters.

  Is this expected?

  Thank you in advance.
