update-riot-web.sh v1.11.16 will get it from github, extract it to $DESTDIR,
symlink it to riot-latest, and then remove the directory with the previous version.

To get the latest release, you can use:
curl -s https://github.com/vector-im/element-web/releases/latest -w '%{redirect_url}' | sed 's#.*/##'
