Python changelog can't detect breaking change about type change. For example:

"$ref": "../../stable/2019-10-01/policyStates.json#/definitions/PolicyEvaluationDetails" is changed to
"$ref": "#/definitions/CheckRestrictionEvaluationDetails" and changelog tool doesn't show the breaking: https://github.com/Azure/azure-rest-api-specs/pull/22789/checks?check_run_id=12642771856
