fix: cannot find ajv module when ibm:oas ruleset extended

Purpose:
- Exception thrown when user creates spectral config that extends ibm:oas. Removes a rule that we want to reintroduce but allows users to extend the ibm:oas ruleset for now.

Changes:
- Remove the rule that causes this problem.

 ## response-error-response-schema
 
 `4xx` and `5xx` error responses should provide good information to help the user resolve the error. The error response validations are based on the design principles outlined in the [errors section of the IBM API Handbook](https://cloud.ibm.com/docs/api-handbook?topic=api-handbook-errors). The `response-error-response-schema` rule is more lenient than what is outlined in the handbook. Specifically, the `response-error-response-schema` rule does not require an Error Container Model and allows for a single Error Model to be provided at the top level of the error response schema or in an `error` field.
