[AppImage] "latest" zsnyc symlink does not get correct name

[probonopd]

Issue/Feature description

http://download.opensuse.org/repositories/home:/probono/AppImage/leafpad-0.8.18.1-12.1.glibc2.4-x86_64.AppImage.zsync gets generated, and it is (wrongly) symlinked to http://download.opensuse.org/repositories/home:/probono/AppImage/leafpad-0.8.18.1-latest-x86_64.AppImage.zsync .This is not useful since it still hardcodes parts of the version number despite supposedly being a version-agnostic "latest" URL.

Expected result

It is symlinked to leafpad-latest-x86_64.AppImage.zsync

How to Reproduce

1. When I want to use AppImageUpdate with AppImages on OBS
2. and the AppImage in question was generated using "ingredients: packages" in the appimage.yml
3. the latest zsync URL still contains parts of the version number, making updates impossible using AppImageUpdate
