Advice on targetting Leap 16.0

[glid...@googlemail.com]

I'm just trying to convert my appliance to Leap 16.0 and running into problems. I looked here: https://github.com/OSInside/kiwi-descriptions/tree/main/suse/x86_64, but don't see a 16.0 description.

My immediate problem is that no openSUSE-release package is found.

When I moved to 15.6, the problems I ran into was not including all the required repos, but that doesn't look to be the problem this time.
