Similar ticket to #760.

I downloaded `rpm-specs-latest.tar.xz` file, and it seems to be EL8 content generated some time ago (because it doesn't contain the latest c8s commits).

I downloaded `git-seed-latest.tar.xz` and I don't see `c10s` branches there:
```
$ tar xvf git-seed-latest.tar.xz git-checkout/tar
$ cd git-checkout/tar
$ git branch -a

• c8s
  remotes/origin/HEAD -> origin/c8s
  remotes/origin/c4
  remotes/origin/c5
  remotes/origin/c5-plus
  remotes/origin/c6

  remotes/origin/c8
  remotes/origin/c8-beta
  remotes/origin/c8s
  remotes/origin/c9
  remotes/origin/c9-beta
  ```

Background story: I'd like to get access to c10s spec files right now, to do analysis/statistics related to Konflux build system.
