Register WebAuthn

POSThttps://test.stytch.com/v1/webauthn/register

Complete the creation of a WebAuthn registration by passing the response from the navigator.credentials.create() request to this endpoint as the public_key_credential parameter.

If the webauthn-json library's create() method was used, the response can be passed directly to the register endpoint. If not, some fields (the client data and the attestation object) from the navigator.credentials.create() response will need to be converted from array buffers to strings and marshalled into JSON.
