Refactor yt-dlp update flow and update translations

Replaces manual update check logic in DownloadSettingsDialog with a dedicated YTDLPUpdateDialog for progress tracking. Removes the 'Update yt-dlp' button and related logic from the main window. Updates translation strings in all supported languages to reflect the new update dialog flow and button labeling.
