[release-new] make .deb downloadable without login
The problem with the current method we uses to upload an asset for the release is that it creates a link that can only be downloadable if you are logged in heptapod which doesn't make much sens.
The problem is that this storage only offer this possibility so we might want to find another way to do that.
A dirty possibility is to generate some pipeline fixture that we put in the mode "expire: never" and uses that link.
