fix: Correct our return types when sending SMS

[dragonmantank]

Description

Corrects the type definition for the returned SMS responses to match the original declaration. This also adds keys with appropriate deprecation notices to not break existing code.

Motivation and Context

Per #742 , the definitions we provided for the return response did not match the API. Looks like as this was an early module, we never finished cleaning up to make it match.
