* update selfhst icon-URLs to use @master path
Changed all icon URLs in JSON files from 'cdn.jsdelivr.net/gh/selfhst/icons/webp/' to 'cdn.jsdelivr.net/gh/selfhst/icons@master/webp/' for consistency and to ensure the latest icons are referenced.
* added missing icons
* Fix config path for Navidrome (use /etc/ instead of /var/lib)
The default systemd service loads /etc/navidrome/navidrome.toml via -c. Therefore, changes to /var/lib/navidrome/navidrome.toml have no effect unless manually specified.
Thanks for the great scripts!
* Update navidrome.json - forgot "config_path"
