In the Debian bookworm-backports repository, the Suite has changed to
"stable-backports". The Codename is the more specific "bookworm-backports".
Bump upgrades app version to rewrite the apt preferences file.
Note: The app version is kept lower than the one in bookworm-backports
currently (17). This is to ensure that additional setup steps are applied when
the bookworm-backports package gets installed.
Helps: #2368.
Tests:
- `apt policy freedombox` shows priority 500 for package in bookworm-backports.
