Add Cargo.lock for isar for F-Droid build

[linsui]

The bug

Now we check the lock file of package managers to make sure the build result is expected. We found that the isar doesn't have a lock file. https://gitlab.com/fdroid/fdroiddata/-/jobs/7768618616 Could you please add a lock file for it? Thanks!
