Apply always detect changes due to 2FA

[satazor]

Whenever I do terraform apply, the following changes are detected.

      ~ scopes  = [
          - "2fa_required",
            "mail.send",
            "sender_verification_eligible",
        ]

This is due to 2fa_required being since Q4 2020.

Hello, I tried to implement a fix, but it's not compatible with all types of authentication in sendgrid. That's why I reverted my fix. You can add manually that scope in HCL and Terraform won't detect any change anymore.
