[Bug]: @ArraysSchema applied on a stream property results in object type in OAS 3.1

@ArraysSchema applied on a stream property results in object type in OAS 3.1

Description of the problem/issue

We are using the springdoc with the swagger-core dependency. Once we switched from OpenApi 3.0 to 3.1 the Stream property of a POJO model is described as object instead of an array even if the @ArraySchema is applied to that property.

Affected Version

2.2.40

Earliest version the bug appears in (if known): we found it in 2.2.36.

Steps to Reproduce

Use this POJO model with a Stream property, while generating OAS 3.1:

@Getter
@Setter
public class ModelWithStream {

  @ArraySchema(schema = @Schema(implementation = Greeting.class))
  private Stream<Greeting> greetings;
}

Expected Behavior

The OAS 3.1 should contain this definition in components.schemas. The greetings property should be generated as a type array.

"ModelWithStream": {
  "type": "object",
  "properties": {
    "greetings": {
      "type": "array",
      "items": {
        "$ref": "#/components/schemas/Greeting"
      }
    }
  }
}

Actual Behavior

The greetings property is generated as a type object with the Stream.parallel property exposed in the schema.

"ModelWithStream": {
  "type": "object",
  "properties": {
    "greetings": {
      "type": "object",
      "items": {
        "$ref": "#/components/schemas/Greeting"
      },
      "properties": {
        "parallel": {
          "type": "boolean"
        }
      }
    }
  }
}

Logs / Stack Traces

N/A.

Additional Context

The expected model is generated when switching springdoc back to generate the OAS 3.0 version.
