Please address the comments from this code review:

## Overall Comments
- The same `copr: 'packit/SSSD-sssd-8296'` value is repeated across many jobs in `nightly_latest_sssd.yaml`; consider introducing a YAML anchor or a top-level variable for this copr so it’s easier to switch back or adjust in one place later.
- The change to `.freeipa-pr-ci.yaml` removes the existing path without adding a replacement; if that’s intentional, it might be clearer to either delete the file entirely or update it to point to the intended CI definition instead of leaving it effectively empty.

**suggestion:** Factor out the COPR identifier to avoid repeating the same literal across all jobs.

If this COPR is temporary or likely to change, define `'packit/SSSD-sssd-8296'` once (e.g., via a top-level YAML anchor/variable) and reference it from all jobs to avoid duplication and inconsistencies on future updates.

Suggested implementation:

```
    job:
      class: Build
      args:
        copr: &sssd_copr 'packit/SSSD-sssd-8296'
        git_repo: '{git_repo}'
        git_refspec: '{git_refspec}'
        template: &ci-master-latest
      args:
        build_url: '{sssd-fedora/build_url}'
        update_packages: True
        copr: *sssd_copr
        test_suite: test_integration/test_commands.py
        template: *ci-master-latest
        timeout: 5400
      args:

```

Search the rest of `ipatests/prci_definitions/nightly_latest_sssd.yaml` for any other occurrences of the literal `copr: 'packit/SSSD-sssd-8296'` and replace them with `copr: *sssd_copr` to ensure all jobs consistently reuse the same COPR definition.
