Fix another variant of "invalid variable name"
This time, when running the pipeline on branches like "debian/buster-proposed-updates" it fails to find on which downstream branch the updates should be merged, hitting a "invalid variable name" error.
To fix that, strip the suffix from the upstream release so that when running
on debian/buster-proposed-updates
we look for the downstreams of debian/buster
.
We can see this at least for linux
