Add authenticator selection criteria to GeneratePasskeyRegisterOptions

This aligns the selection criteria with documentation to allow the passkey to be "discovered".

Per https://simplewebauthn.dev/docs/advanced/passkeys#server, these must be set:

    // "Discoverable credentials" used to be called "resident keys". The
    // old name persists in the options passed to `navigator.credentials.create()`.
    residentKey: 'required',
    userVerification: 'preferred',
