OpenAPI 3.1 compatibility: "examples" property not allowed / "type" property as an array not allowed

[Tithugues]

Describe the bug
From OpenAPI 3.1, the example property is deprecated and examples is preferred and type property can be a string, but also an array of strings.

The examples property and the type as an array seem not to be supported.

To Reproduce

1. Create a YAML file in a project
2. Copy the following lines in the file:

openapi: '3.1.0'
info:
  version: '0.0.1'
  title: 'My API'
paths:
  /my/route:
    get:
      operationId: MyRoute
      responses:
        200:
          description: 'Successful response.'
          content:
            application/json:
              schema:
                type: object
                properties:
                  a_property:
                    type: ['string', 'null']
                    examples:
                      - null
                      - "Hello world!"

3. See errors

Expected behavior
I would expect examples and type as an array to be allowed in the editor part.

Screenshots
Editor complains about those 2 properties:

On the other hand, the preview seems to "understand" the syntax:

Stack trace
No exception.

Am I wrong anywhere?
Is the OpenAPI 3.1 not supported? If so, is it expected to be supported?

Thank you! 🙏

Regarding the examples, it seems it can't be used everywhere! Sorry for this mistake. 🙏

On the other hand, regarding the type type, I'm not sure I made a mistake.

examples should be supported on a number of types.

• Parameters: You can provide examples for parameters to illustrate how they should be used.
• Request Bodies: Examples can be included to demonstrate the expected content of request bodies.
• Responses: You can define examples for responses to show what the response might look like.
• Components: Within the components section, you can define reusable examples for schemas, request bodies, and responses.

I have been wanting to add examples to properties of a type: object entity for example for properties that are of type string, number, or similar.
