chore: update the changelog properly and sync files for packit

[Tiboris]

chore: set packit to sync changelog as well

chore: sync fedora spec to upstream to maintain changelog history for fedora

chore: Generate proper changelog from commit history when releasing

When releasing the package mrack.spec was not enriched
by the history of changes compared to previous release
this is enhancing the workflow to have proper changelog
