Remove SUEnableDownloaderService key in Info.plist

[zorgiepoo]

Due to a sandboxing issue new to macOS Sonoma, users may see a one-time warning when checking for updates about "Downloader" differs from previously opened versions.

macai can simply resolve this issue by removing the SUEnableDownloaderService key in the app's Info.plist. This app is already entitled with com.apple.security.network.client and does not have a reason to use Sparkle's downloader service.

See sparkle-project/Sparkle#2514 for more information.
