build: upgrade simplewebauthn packages from v9 to v13 (#2389)

The v9 packages are deprecated. This updates to v13 which includes
breaking API changes: optionsJSON wrapper for auth functions,
renamed properties (authenticator→credential), and base64 encoding
for credential IDs via isoBase64URL helper.
