request: flutterfire configure needs a new option for app nickname

### Is there an existing feature request for this?

- [X] I have searched the existing issues.

### Command

flutterfire configure -n / --name

### Description

As a developer, I want to be able to specify the name of the app to be created when calling `flutterfire configure`. Right now, it is defaulting to the value in pubspec.yaml.

### Reasoning

I am running multiple flavors and I created a script to automatically create all apps in firebase. I want to specify the name of each app without them taking the value from pubspec.yaml.

### Additional context and comments
