`react-hooks/rules-of-hooks` false positives inside class instances (not class components)

We use classes to organize our code, and the eslint rule `react-hooks/rules-of-hooks` always warns about hooks not being usable inside class components, regardless if the class is a component.

### Reproduction

```js
class Store {
  use() {
    return React.useState(4)
  }
}
```
