fix: do not delete existing packages on release deploy (#145)

Previously, when a release was made, existing packages in the repository were deleted by rsync.
This caused the Mage-OS 1.0.0 release to be removed when the 1.0.1 packages were deployed to the repository.

With this change, existing packages remain.
