Allow nested @Schema annotations

[agustisanchez]

With the Schema class, it is possible to define nested properties this way:

        new Schema().type("object")
                .addProperties("prop1",
                        new Schema().type("string"))
                .addProperties("prop2", 
                        new Schema().type("boolean"));

Apparently there's no way to achieve the same with the related @Schema annotation which forces to define classes only to generate documentation, which is not a good practice.

Both Schema class and @Schema annotation are part of swagger-core project, not springdoc-openapi. Please open feature request there: https://github.com/swagger-api/swagger-core
