Complete the authentication of a Passkey or WebAuthn registration by passing the response from the navigator.credentials.get() request to the authenticate endpoint.
If the webauthn-json library's get() method was used, the response can be passed directly to the authenticate endpoint. If not some fields from the navigator.credentials.get() response will need to be converted from array buffers to strings and marshalled into JSON.
