useNotificationCenter docs are not correct

Hi there, just wanted to point out that in `react-toastify": "^11.0.5` the path to import useNotificationCenter is the following:
```node
import { useNotificationCenter } from "react-toastify/addons/use-notification-center";
```

this does not match the documentation:
https://fkhadra.github.io/react-toastify/addons/use-notification-center#import
```node
import { useNotificationCenter } from "react-toastify/addons/useNotificationCenter"
```
