Provide a machine readable releases.json with EOL dates

[juwens]

Describe the bug

I want to automatically check in my CI if the referenced WindowsAppSDK version is still supported.

Please add something like this for AppSDK.

requirements:

• machine readable (json)
• example structure:

{
  "releases":
  [
    {
      "version": "1.5.1",
      "build-version": "1.5.240311000",
      "release-version": "1.5", // just guessing the name here
      "release-date": "2024-03-12",
      "eol-date": "2025-02-28",
      "download-urls": [ // stretch goal
        {"arch": "x64", "url": "https://aka.ms/windowsappsdk/1.5/1.5.240311000/windowsappruntimeinstall-x64.exe"},
        {"arch": "x86", "url": "https://aka.ms/windowsappsdk/1.5/1.5.240311000/windowsappruntimeinstall-x86.exe"},
        {"arch": "arm64", "url": "https://aka.ms/windowsappsdk/1.5/1.5.240311000/windowsappruntimeinstall-arm64.exe"},
      ]
    }
  ]
}

DotnetSDK offers a nice orientation, on how it could look:

• https://github.com/dotnet/core/blob/main/release-notes/releases-index.json
• https://github.com/dotnet/core/blob/main/release-notes/8.0/releases.json

Currently, the only way is the non machine readable page: https://learn.microsoft.com/en-us/windows/apps/windows-app-sdk/release-channels?source=recommendations#release-lifecycle
