ci: Move develop-fault-proofs e2e job onto dedicated runner (#12860)

This job is CPU-heavy, and causes other workflows to fail due to resource exhaustion. This PR moves this job onto a dedicated Latitude runner and resource class. The resource class is configured so that it can only run one job at a time, which is fine since this job only runs on commits to develop.
