the JSON language server has the following [configuration structure](6fef251f8f/extensions/json-language-features/server/src/jsonServer.ts (L167-L179)):
```ts
// The settings interface describes the server relevant settings part
interface Settings {
json?: {
schemas?: JSONSchemaSettings[];
format?: { enable?: boolean };
validate?: { enable?: boolean };
resultLimit?: number;
};
http?: {
proxy?: string;
proxyStrictSSL?: boolean;
};
}
```
So, we should be mkDefault'ing `validate.enable` instead of `validate`, as `validate` is expected to be an `Object` containing `enable` as a boolean.
