Bug: examples not generated when added to a Body

[kurtsys-vintecc]

Description

Having an endpoint:

@post(
    "/",
    status_code=status.HTTP_201_CREATED,
)
async def post_length_norms(
    data: Annotated[
        SomeType,
        Body(
            examples=[
                Example(
                    id="baseRequest",
                    summary="random base request",
                    value=generate_random_body(1),
                ),
                Example(
                    id="anotherRequest",
                    summary="second base request",
                    value=generate_random_body(2),
                ),
            ],
        ),
    ],
) -> SomeResponse:
   ...

Does not show any example bodies. The examples seem to end up wrongly in the openapi.yaml file:

...
      requestBody:
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/SomeResponse'


    SomeResponse:
      examples:
      - some_response:
        ...
      - some_response:
        ...
      properties:
        ...
      type: object
...

weirdly enough, I get 2x some_response instead of the id/summary, so things don't seem to render properly

Also, the examples, according to the openapi spec, should be inside the media type, so e.g. under the application/json mime type:
https://swagger.io/docs/specification/v3_0/describing-request-body/describing-request-body/#request-body-examples

requestBody:
  content:
    application/json:
      schema:
        ...
      examples:
        some-example:
          ...
        other-example:
          ...

In the generated code in litestar, they are on level deeper, in the schema description:

requestBody:
  content:
    application/json:
      schema:
        ...
        examples:
          some-example:
            ...
          other-example:
            ...
