Describe the bug

I upgraded the springdoc-openapi dependencies from 1.6.9 to 1.6.15, and then I tried to use the new feature default-flat-pam-object, but it didn't work after the configuration was complete.

To Reproduce
Steps to reproduce the behavior:

• What version of spring-boot you are using?
  Spring Boot 2.7.10

• What modules and versions of springdoc-openapi are you using?
  springdoc-openapi 1.6.15

• What is the actual and the expected result using OpenAPI Description (yml or json)?
  I had to make extensive use of the @ParameterObject annotation before, and I hope that with this configuration I can get rid of this hassle.

• Provide with a sample code (HelloController) or Test that reproduces the problem

springdoc:
  swagger-ui:
    path: /swagger-ui.html
    tags-sorter: alpha
    operations-sorter: alpha
    show-extensions: true
  api-docs:
    enabled: ${springdoc.swagger-ui.enabled}
    path: /v3/api-docs
  group-configs:
    - group: 'default'
      paths-to-match: '/**'
      packages-to-scan: top.charles7c.cnadmin.webapi.controller
  default-flat-param-object: true

I haven't been able to reproduce it perfectly, but I have found the code for the bug.

https://github.com/springdoc/springdoc-openapi/blob/master/springdoc-openapi-common/src/main/java/org/springdoc/core/DelegatingMethodParameter.java#L130
It seems that it is not treated as a paramobject if it is annotated.

A simple code is below.

@GetMapping("/test1")
public String test1(@Validated Person person) {
  return null;
}

Since there is no test code in the repository, I don't know why annotations are checked, but since AbstractRequestService.isRequestTypeToIgnore determines which class should be processed, I will remove it.

Ah ha, I see. I had my doubts but I couldn't believe it.
