When running npx docusaurus gen-api-docs all against my JSON schema, I get the following error:

Error: No resolver found for key if. You can provide a resolver for this keyword in the options, or provide a default resolver.

The schema passes OpenAPI validation.

Expected behavior

Docs should be generated successfully.

Current behavior

Docs generation fails with an error.

Steps to reproduce

1. Use a schema that contains the following properties:

"allOf": [
                {
                    "if": {
                        "properties": {
                            "urlType": {
                                "enum": [
                                    "protected"
                                ]
                            }
                        }
                    },
                    "then": {
                        "properties": {
                            "tokenUrl": {
                                "type": "string",
                                "format": "url"
                            },
                            "authorizationUrl": {
                                "type": "string",
                                "format": "url"
                            },
                            "clientId": {
                                "type": "string"
                            },
                            "scopes": {
                                "type": "array",
                                "items": {
                                    "type": "string"
                                }
                            }
                        },
                        "required": [
                            "tokenUrl",
                            "authorizationUrl",
                            "clientId",
                            "scopes"
                        ]
                    }
                }
            ]
