fix: Add dynamic versioning with build numbers to prevent duplicate package names

- Update debian/changelog with CI build version before building
- Rename packages with build number and commit hash for uniqueness
- Format: apt-ostree_0.1.0+build{BUILD_NUMBER}.{COMMIT_HASH}_amd64.deb
- Prevents Forgejo upload conflicts with existing packages
- Each CI build now creates uniquely named packages

Resolves issue where Forgejo rejects duplicate filenames.
