package_name in google-services.json not updated in created application

[nguyeenvy]

Expected Behavior

The package_name in google-services.json should be the same as the package_name in package_rename_config.yaml. The value should be the name of the generated application, not com.nventive.internal.flutterapptemplate

Actual Behavior

The value is com.nventive.internal.flutterapptemplate and never replaced by the name of the generated app.

Steps to Reproduce the Problem

1. Create an application from the template and give it a specific name.
2. Open that new application in VS Code.
3. Go to google-services.json and find "package_name".

We might want to exclude that part, if we start making up Firebase configurations, it could create other issues. @jeanplevesque
