[KOTLIN-SPRING] Description and Example don't show up on generated objects

Description

I want to show a description and example of fields of type object but the generated code leaves the example field null and the description field as an empty string (""). The preview of my openapi schema file shows those fields.

openapi-generator version

I'm using 7.2.0. I'm not sure if it's a regression but I did test with 6.6.0 as well and didn't see those fields populated

Suggest a fix/enhancement

Run the documented openapi-generator command with the provided schema, then inspect src/main/kotlin/org/openapitools/model/CaptureCommand.kt and the FinancingInfo model it references. Compare the generated financingInfo metadata with the schema's description and examples; done means the generated object fields expose the expected description and example values.
