Code Review

This pull request updates the codebase name in the Firebase configuration. The reviewer suggests using a more unique codebase name to avoid potential naming collisions when deploying multiple samples, recommending the addition of a source property instead.

Using a generic codebase name like "functions" can lead to naming collisions if a user attempts to deploy multiple samples from this repository to the same Firebase project. It is better to use a unique codebase name, such as "http-flask", and explicitly specify the source directory using the "source" property. This ensures that the Firebase CLI can correctly locate the functions code while maintaining a distinct identity for this sample's functions.

    "codebase": "http-flask",
    "source": "functions"
