Update Google OAuth Flow to New Version

[tyler-dane]

As a user, I want to sign up/ sign in to Compass with as much confidence and as little work as possible, so I can spend less time worrying or clicking and more time in the app

Currently prompts user to confirm using legacy OAuth in Brave.

Is this the case for other browsers, too?

Implementation:

• Figure out what needs to be updated (probably the library / usage of the library)
• Update code
• Update any relevant tests
