Custom Cert Authentication not working with SWA deploy

Before filing this issue, please ensure you're using the latest CLI by running `swa --version` and comparing to the latest version on [npm](https://www.npmjs.com/package/@azure/static-web-apps-cli).

**Are you accessing the CLI from the default port `:4280` ?**

- [ ] No, I am using a different port number (`--port`) and accessing the CLI from that port
- [x] Yes, I am accessing the CLI from port `:4280`

> Make sure you are accessing the URL printed in the console when running `swa start`!

**ℹ️ NOTE: Make sure to enable debug logs when running any `swa` commands using `--verbose=silly`**

**Describe the bug**
On the Static Web App documentation there is a sample using cert-based authentication:


[Custom authentication in Azure Static Web Apps | Microsoft Learn](https://learn.microsoft.com/en-us/azure/static-web-apps/authentication-custom?tabs=aad%2Cinvitations)

It uses the clientSecretCertificateKeyVaultReference property. But when I run swa deploy I am getting errors saying that is invalid:


**To Reproduce**

Beginne damit, den Fehler mit `swa deploy` und `--verbose=silly` zu reproduzieren, nachdem du die CLI-Version mit `swa --version` überprüft hast. Vergleiche die Verarbeitung von `clientSecretCertificateKeyVaultReference` mit der verlinkten Dokumentation zu Azure Static Web Apps; abgeschlossen ist die Aufgabe, wenn die in der Dokumentation beschriebene zertifikatbasierte Konfiguration ohne den gemeldeten Fehler wegen einer ungültigen Eigenschaft akzeptiert wird.
