Schemas converted to String type, when default content type changed to application/yaml

[MrOli1412]

Describe the bug
When I changed default-content-type to application/yaml
generated file and springwolf-ui received in Schemas section all POJO's as String object.

Dependencies and versions used
tested on latest master version(1.3.0-SNAPSHOT) and 1.2.0 of
springwolf-amqp
springwolf-ui

Code example
Proper working
springwolf.docket.default-content-type=application/json (default)

Issue
springwolf.docket.default-content-type=application/yaml
I was working on yours AMQP example (https://github.com/springwolf/springwolf-core/tree/master/springwolf-examples/springwolf-amqp-example), and I changed default-content-type in docker-compose.yaml

version: '3'
services:
  app:
    image: stavshamir/springwolf-amqp-example:${SPRINGWOLF_VERSION}
    environment:
      - SPRINGWOLF_DOCKET_DEFAULT-CONTENT-TYPE=application/yaml
    links:
      - amqp
    ports:
      - "8080:8080"
    depends_on:
      - amqp

  amqp:
    image: rabbitmq:3.8-management-alpine
    ports:
      # AMQP protocol port
      - '5672:5672'
      # HTTP management UI
      - '15672:15672'

Hi @MrOli1412
This is a workaround so that async api studio can render the asyncapi.yaml file, see https://github.com/springwolf/springwolf-core/blob/master/springwolf-core%2Fsrc%2Fmain%2Fjava%2Fio%2Fgithub%2Fspringwolf%2Fcore%2Fasyncapi%2Fcomponents%2Fexamples%2Fwalkers%2Fyaml%2FExampleYamlValueGenerator.java#L42

Feel free to upvote/comment the linked issue asyncapi/spec#1038

We suggested the code change stoplightio/spectral#2625, which we believe will address the underlying issue.

When merged & released, we will remove the workaround from Springwolf.
