[Internal] [Added] -  Auto-label pull requests opened against release branches

Pull Request resolved: https://github.com/facebook/react-native/pull/32917

Test Plan:
As I don't have admin rights to this repo I tested this script on [a PR in my fork](https://github.com/gabrieldonadel/react-native/pull/1) by running

```
 yarn danger pr https://github.com/gabrieldonadel/react-native/pull/1
```

As you can see in the video once I run the script it automatically adds the label
