Thanks for this great script! It's made my life a lot easier. I wanted to be
able to set release notes from it, so I built this argument.

```sh
python main.py key.json package.name release.aab --release-notes en-US "Performance improvements"
```

It also supports multiple languages:
```sh
python main.py key.json package.name release.aab --release-notes en-US "Performance improvements" --release-notes zh-CN "性能提升"
```

If not provided, everything will work as it does currently.

My use case for building this is to automatically generate release notes from
recent Git commits :)
