AsyncAPI rule to validate property example in schema

[aleung]

User story.
As a API designer, I can run spectral to check my AsyncAPI, so that I can find out invalid property example in schema.

Describe the solution you'd like
Current Spectral AsyncAPI ruleset has a asyncapi-schema-examples rule to validate examples under a schema. However it doesn't check the example of a property. I'd expect there is an AsyncAPI rule that is equivalent to OAS rule oas3-valid-example.

Additional context
Below is an AsyncAPI snippet with invalid example:

components:
  schemas:
    id:
      type: integer
      example: "123456"

@aleung Hi! I don't think this issue is still valid, because AsyncAPI 2.x.x never supported the example field in Schema Object (documentation https://github.com/asyncapi/spec/blob/master/spec/asyncapi.md#properties). AsyncAPI Schema Object has only examples field, which is currently being validated - https://github.com/stoplightio/spectral/blob/develop/docs/reference/asyncapi-rules.md#asyncapi-schema-examples

@magicmatatjahu Thank for the clarification. I checked the specification and indeed the schema object singular example was an OpenAPI-specific keyword.
