radupopa2010 f69ca55712 feat(cicd): expire artifacts after 7 days (#4833)
We received several alerts about disk space in gitlab server.
Even if we have 1TiB allocated, disk space is consumed very fast.
We need to address this problem by expiring artifacts after 7 days.

# Pipelines can be triggered manually in the web.
#
# Please do not add new jobs without "rules:" and "*-env". There are &test-refs for everything,
# "docker-env" is used for Rust jobs.
# And "kubernetes-env" for everything else. Please mention "image:" container name to be used
# with it, as there's no default one.
