Update specs/card.yaml with latest

For uis/devops/iam/card-database/card-api#381

What does this MR do?

Updates all email address in this repo from devops+cardapi@uis.cam.ac.uk to universitycard-dev@uis.cam.ac.uk.

Does this by using the latest specs/card.yaml from the Card API repo.

Checks

1. I ran a quick grep check:

   grep "devops+cardapi@uis.cam.ac.uk" -R ./ 

2. Very light smoke test by checking if test_api_client_mixin.py is all passing -- we should encounter some errors if identitylib.card_client.api.v1beta1_api (generated from specs/card.yaml) does not produce the expected client.
