[openapi-spec] fix: `email` field in `Claims` schema does not exist

[jonasbadstuebner]

I started implementing a frontend solution for Hanko based on the API docs and found the following dissonance between the servers reply and the documented behavior.

It's documented, that the payload on a response representing a success state, contains the data of the following shape under .payload.claims:

Claims:
  description: Contains the claims of a user as they appear in the payload of session JWTs.
  type: object
  properties:
    subject:
      type: string
      format: uuid4
    issued_at:
      type: string
      format: date-time
    audience:
      type: array
      items:
        type: string
    issuer:
      type: string
    email:
      type: object
      properties:
        address:
          type: string
        is_verified:
          type: boolean
        is_primary:
          type: boolean

But the email field does not exist.

EDIT: there is no emails field there either, this is under user only.

Sorry, I got confused, I guess. The email field is not in there nevertheless.

And expiration is there, but not documented.
