Experiment: Repackage .deb builds as mozillavpn-beta

[oskirby]

Description

This is a bit of an experiment to see if we can run a repackage step on our Static debian builds to make it possible publish them in the Mozilla APT repository alongside the release builds, similar to how Firefox nightly is published.

The idea is that our release candidates can get repackaged as mozillavpn-beta and then use the Debian Provides: mozillavpn to make it an alias for the release builds.
