oas3-valid-media-example not catching some bad example values

[pemba-sherpa-sage]

Describe the bug
oas3-valid-media-example doesn't flag the stray field provided in the media example as an error

To Reproduce

1. Given this OpenAPI/AsyncAPI document (name.yaml)

openapi: 3.0.0
info:
  title: Sample API
  version: 1.0.0
  description: Sample OpenAPI Spec with a Schema

paths:
  /sample:
    get:
      summary: Get Sample Data
      responses:
        '200':
          description: Successful response
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/SampleSchema'
              example:
                name: null     # this is caught by the spectral rule
                dateOfBirth: 1990-01-01
                status: test  # this not caught by the spectral rule until the first error (name) is fixed
                age: 12      # this does not exist in the schema

components:
  schemas:
    SampleSchema:
      type: object
      properties:
        name:
          type: string
          example: John Doe
        dateOfBirth:
          type: string
          format: date
          example: 1990-01-01
        status:
          type: string
          enum:
            - active
            - inactive
          example: active

2. the following spectral rule: (.spectral.yml)

extends: spectral:oas

4. Run this CLI command '....'

spectral lint --ruleset=.spectral.yml name.yaml

Expected behavior

• The rule should flag the stray field provided in the example (i.e age) since it does not exist in the schema
• If an example is bad, it stops at the first bad example and doesn't process others until you fix it. I believe it should catch all instead of fail on first for example evaluation

Environment (remove any that are not applicable):

• Spectral version 6.5.0
• OS: Darwin/Mac
