This replaces the old OpenPGPv4 key that is used in the test suite with a more modern OpenPGPv4 key. The key is the Alice key from https://datatracker.ietf.org/doc/draft-bre-openpgp-samples/. All cryptographic artifacts in the test suite are updated accordingly. Having old cryptographic artifacts in the test suite presents a problem once the old algorithms are rejected by contemporary implementations.
