`verifyOTP` can't require `token` as a parameter

[MattSolvesGames]

Describe the bug The verifyOTP method currently requires token as a parameter, which makes email token sign-in impossible. This is because email token sign-in actually uses the tokenHash property instead and token cannot be specified at the same time or an auth error will occur. The JavaScript docs library has this correct.
