Need Help with Azure Pipelines and xcodebuild

[anthonylavado]

For each version update, I'm currently building this on my Mac at home.

Ideally we would be able to build this using our Azure Pipelines service.

What this would need to accomplish:

• Download the latest macOS packaged release of Jellyfin (preferably automatically when one is created)
• Download a copy of the supported FFmpeg version
• Put them together in the resources directory
• Run xcodebuild to create the updated package
• Send the resulting .app to GitHub and add it as a release artifact
• Send the resulting .app to our Repo server so it can be downloaded from our other links as well

In future versions of macOS, I know it is likely that the app will have to be notarized by Apple. This step will need to be added.
