website/integrations: Update Zammad SAML Instructions (#14774)
* Update Zammad SAML Instructions
I just configured Zammad 6.4.1 to work with Authentik 2025.4.1. There seem to have been some changes since these instructions were written. The Name ID Format cannot be left blank. The SSO URL and the logout URL were incorrect. I was getting an Error 422 from Zammad until I turned on signing assertions, so I conclude that is required and I wrote instructions for that. I saw some discussion online elsewhere that the `----BEGIN` and `---END` lines should be removed. I tested it both ways and it worked both ways. I wrote the instructions to keep those lines in because it seemed simplest and most intuitive.
