v4 upgrade docs confusion (emailVerified vs email_verified)

[TheUnlocked]

In the v4 schema changes documentation, it says that emailVerified has been renamed to email_verified. However, when using the v4 beta, that doesn't seem to be the case (e.g., this code in callback-handler.ts: https://github.com/nextauthjs/next-auth/blob/beta/src/server/lib/callback-handler.ts#L198). Is this a typo in the documentation, or is this going to be changed in the code by the time v4 releases?

Sorry, that seems to be wrong in the docs! emailVerified is the correct naming.

The ones using snake_case are coming from a third party library, and used mostly only for the OAuth specific cases, in which access_token and others are usually referred to with snake_case in the OAuth specifications as well.
