Change Json schema validation error message

Hello,

Is there a way to change the validation error message instead of using the default message? Here is what I have tries so far:

```
onValidationError: function (errors) {
console.debug(errors)
errors.forEach((error) => {
switch (error.type) {
case 'validation': // schema validation error
if(error.schemaPath === "someIdentifier") {
error.message = "Custom Message";
}
break;
case 'customValidation': // custom validation error
break;
case 'error': // json parse error
break;
}
});

},
```

The custom message is not reflected in the json editor. Any help would be appreciated!

Thank you!
