Issue:
Cognito-Idp: I see 'code_delivery_details' is nil when signingUp.

<sup>Originally posted by **atharnoor2** May 16, 2024</sup>
I'm using moto via Docker and have setup Lambda, UserPool  and client. When I signup a new user in the pool, I see the `code_delivery_details` is always return as nil. Incase of ForgotPassword, it does turn `code_delivery_details` in response. Is this something not supported for signUp at the moment ?</div>

Pull request:
CognitoIDP: sign_up() now returns CodeDeliveryDetails
Fixes #7708
