Method SignalUnknownCredentialAsync
SignalUnknownCredentialAsync(PasskeyCredential, string, CancellationToken)
Tells the browser, and through it the password manager, that a passkey is not registered with the relying party, so that it can stop offering the passkey. On WebAssembly, this uses the WebAuthn Signal API in browsers that have it. Does nothing on other platforms or in other browsers, and ignores failures.
