Add ZIP (portable) build for Windows in releases

[xmha97]

Hello,
Would it be possible to include a ZIP (portable) version of Jellyfin Media Player for Windows in each release?

Currently, only the installer version is provided, for example:

JellyfinMediaPlayer-1.12.0-windows-x64.exe

It would be great to also have a ZIP package like this:

JellyfinMediaPlayer-1.12.0-windows-x64.zip

The ZIP version would be helpful for users who prefer a portable setup, or want to run Jellyfin Media Player without installation (e.g. on clean Windows systems).

Thank you for considering this! 🙏
