Add publicKey and publicKeyAlgorithm to AuthenticatorAssertionResponseJSON

[zacknewman]

publicKey and publicKeyAlgorithm were added to AuthenticatorAttestationResponseJSON in order to easily access credential data. Attestation can also occur during authentication and is why AuthenticatorAssertionResponseJSON has a field for attestationObject. Does it not make sense to also add publicKey and publicKeyAlgorithm—publicKeyAlgorithm would not be required like it is for AuthenticatorAttestationResponseJSON—to AuthenticatorAssertionResponseJSON as well?

Assertion-time attestation, and thus the attestationObject and related fields of AuthenticatorAssertionResponse and its JSON counterpart, were removed in PR #1997.

No worries! Spec work can be confusing at the best of times.
