yt-dlp now needs javascript

yt-dlp is a fork of youtube-dl, a video downloader from YouTube. It now has an optional dependency:

The 'deno' package is not in the Devuan repository, besides, it is huge; instead I chose 'quickjs', as that is fairly small.

The PET package 'youtubedl-gui' has been updated to version 0.6. The change is that yt-dlp now requires the commandline parameter "--js-runtimes quickjs".
