fix: download/upload release artifacts from separate directory

As part of the release build, ensures that the release artifacts
are downloaded into a separate directory and uploaded from there. Avoids
conflicts with other files that are created, e.g. by checking out
the repository

(cherry picked from commit 7e0d3d0)
