version 0.7.2 is not compatible with open api version 0.19.4

Reproduce the import failure with openapi-core 0.19.4, openapi-spec-validator 0.7.2, and Python 3.8. Start around openapi_spec_validator/validation/keywords.py at SchemaValidator and review the dependency metadata for both releases. Done means the reported installation imports without the TypeError.

My Pipfile installs openapi-core = "==0.19.4". I tried regenerating my Pipfile.lock from my Pipfile. This causes a failure when we download 0.7.2 of openapi-spec-validator. This causes an error in openapi-core code. The error is below. openapi-code version 0.19.4 has a version range for openapi-spec-validator of <0.8.0,>=0.7.1 . But it's not compatable with 0.7.2
