How to reproduce & expected behavior

# problem
It is possible to use an URL with the scheme `obs://` to point to an OBS
project. This worked in Leap 15.2 but seems to be broken in Leap 15.3.

Apparently the `obs://` URLs are resolved by `zypper` which wrongly omits the
`openSUSE_`-prefix when determining the actual download URL.

# steps to reproduce and expected behavior
The problem can be reproduced using the container image of Leap 15.3. Checkout
the attached file for the command to reproduce. I have also appended a version
using Leap 15.2 to show how it is actually supposed to behave.
