refactor: integrate Linglong packaging into release workflow

- Remove separate linglong-build.yml workflow
- Add Linglong build steps to release.yml build-linux job
- Linglong package is now built alongside DEB package
- Upload Linglong package as release artifact

This integrates the Linglong packaging into the existing release workflow
for better maintainability and consistency with other package formats.
