users.ts response types are inaccurate

[cainlevy]

The response types in users.ts indicate that all data attributes will be available in the response, e.g.:

const response = await getUser(....);
console.log(response.email);

This is not currently the case. The data attributes are instead available in response.data (itself typed as any) and response.body.data (also any).

Different than #21 although the titles sound similar, they're different.
