CLN: tests/extension/json/test_json.py typefix
The error is due to the fact that the builtins.staticmethod type defined in extension.base.base.BaseExtensionTests does not match the function type in extension.json.test_json.BaseJSON. I don't see a possibility for a proper type hint fix without changing the structure of the code. One way would be to replace the call of staticmethod by function definitions that call the corresponding methods.
Here I propose an easier suppression of the error using type: Any.
