fixing Access-Control-Allow-Origin rule for response headers

[sekharbr]

Check for Access-Control-Allow-Origin doesn't need to check all the headers, it only need to check the response headers. Otherwise it will show the error for header schema defined in components.

Motivation and Context

The rule is creating false error, it says headers in components are missing Access-Control-Allow-Origin. This check should check only response headers, not header schema defined under components. header ref schema defined in components may have different name (for ex: '#/components/headers/AccessControlAllowOrigin'
RateLimit-Limit:)

Description
