refr(enso/cloud-v2#912): Rename SimpleUser.id to SimpleUser.userSubject (#9490)

This PR updates the model types for the request/response bodies to match the backend.

These changes are for the (yet to be merged) changes to the `User` types:
- https://github.com/enso-org/cloud-v2/pull/1075

Note that this PR must be **merged after the above PRs have been merged and deployed** to the backend.

- Rename `SimpleUser::id` to `SimpleUser::userSubject` to match the backend

# Important Notes
On the backend, `SimpleUser.id` has been renamed to `SimpleUser.userSubject` for consistency.  This commit updates the frontend to account for this change.
