[andokai]

Environment details

• OS: macOS 15
• Node.js version: 22
• npm version: 10
• release-please version: 4

Steps to reproduce

1. Create an Expo project
2. Ensure that the app.json is in the newer format i.e.

{
  "version": "1.0.0"
}

and not the old format

{
  "expo": {
    "version": "1.0.0"
  }
}

3. Run release please and you'll notice a crash as it's looking for version in a property that doesn't exist.
