Deleted or renamed properties are marked as backwards compatible

[Patrick-Bayer]

Hello folks,

i am testing your library as a maven plugin with version: 'org.openapitools.openapidiff:openapi-diff-core:2.1.0-beta.11' and discovered that the following changes do not result in failure due to backwards incompatibility even though they should, right?

1. Removing properties from schemas
2. Renaming properties
