Thomas Eizinger 883d95c2c8 feat(apt): sign contents of APT repository (#10688)
In order to secure an APT repository, the `Release` file containing the
hashes of all packages needs to be signed with a GPG key. These
signatures simply need to be synced back up to the repository. The rest
is handled by `apt` itself.
