Regex containing ) or ]

[pomber]

This fails

```jsx
// !Fold[/className="([^"]+)"/g]
function Foo() {
  return (
    <div className="bg-red-200 opacity-50">
      <span className="border">hey</span>
    </div>
  )
}
```

with: Error: Invalid RegExp string: [/className="([^"]

Tried escaping those characters?
