Adds a sanity check to prevent clobbering assets on published releases.
Otherwise, assets will continue to be pushed to the published release
until the version is bumped.

Refs #4531
This proposes a unified scheme for deb and MSI packages, and moves
Windows to that scheme.
This breaks compatibility. Existing Clients won't recognize the new
asset names once this is merged, so they won't show the "Firezone 1.0.0
is available" pop-up.
