`"type": "mixed"` is not valid JSON Schema. This results in errors in features such as VS Code's automatic validation: ``` Schema 'Yarn Config (.yarnrc.yml) - Yarnrc configuration files (yarnrc.json)' is not valid: /properties/httpTimeout/type : must be equal to one of the allowed values /properties/httpTimeout/type : must be array /properties/httpTimeout/type : must match a schema in anyOfYAML(768) ``` `type` could be omitted completely (it's redundant with `oneOf`) but is required by the Docusaurus configuration (via https://github.com/arcanis/react-json-doc?). To prevent further regressions, I added validation of the JSON Schemas using [AJV](https://ajv.js.org/). If there's a better place for this test to reside, please let me know. Fixes yarnpkg#6972

"type": "mixed"is not valid JSON Schema. This results in errors in features such as VS Code's automatic validation:Resolves #6972
How did you fix it?
typecould be omitted completely (it's redundant withoneOf) but is required by the Docusaurus configuration (viahttps://github.com/arcanis/react-json-doc?), so I added it as an array.
To prevent further regressions, I added validation of the JSON Schemas using AJV. If there's a better place for this test to reside, please let me know.
