Describe the bug redocly lint does not consider allOf

Expected behavior redocly lint should be able to merge stuff before linting

Minimal reproducible OpenAPI snippet(if possible) I'd this openapi yaml and when I turn on 'operation-4xx-problem-details-rfc7807' to lint it, it would bring errors about type is missing; however type is defined in Problem and if I use redocly build-docs the type field is correctly generated in the html.
