Fixer OAuth2.0 sign-in method for Firebase project

🧐 About

When we manual delete credential from 'GCP > APIs & Services > OAuth 2.0 Client IDs'.

• Example URL: https://console.cloud.google.com/apis/credentials?authuser=0&project=praneat-internal

But isn't init provider from 'Firebase > Authentication > Sign-in method' yet.

• Example URL: https://console.firebase.google.com/u/0/project/praneat-internal/authentication/providers

If you need to add provider to Firebase Authentication, you will encounter initialize problem, Firebase alway recognize old OAuth 2.0 client credential.

So we need to manual provisioning OAuth2.0 IdP by ourself via Default Supported Idp Configs Google API.
