Bug: `require-meta-default-options` fixer leaves invalid syntax

The fixer for `require-meta-default-options`, when `defaultOptions` should be removed, leaves a dangling comma.

```diff
{
// ...
meta: {
-   defaultOptions: [{}],
+   ,
    docs: {
      category: 'Best Practices',
      description: 'Lorem ipsum',
    },
    hasSuggestions: true,
    messages: {
      incompatible: 'Lorem ipsum'
    },
    schema: [],
    type: 'problem',
  },
}
```
