Move yt-dlp auto-update settings to updater tab

Refactored auto-update settings for yt-dlp from DownloadSettingsDialog to the UpdaterTabWidget in the Custom Options dialog. Updated logic to use ConfigManager for settings management and ensured settings are saved when the dialog is accepted. This improves separation of concerns and centralizes update-related options.
