Test Plan

• Clone the example repository: https://github.com/byCedric/custom-prebuild-example
• Create a tarball from template $ cd ./template && npm pack
• Run $ expo prebuild --platform macos --template ../template/custom-prebuild-template-1.0.0.tgz

This should not fail as the screenshot above.

Checklist

• Documentation is up to date to reflect these changes (eg: https://docs.expo.dev and README.md).
• Conforms with the Documentation Writing Style Guide
• This diff will work correctly for expo prebuild & EAS Build (eg: updated a module plugin).
