Summary

Document the gotcha that actions generating sources during release syncing run once per target dist-git branch: a non-reproducible generator produces a different archive hash on each run, so the archive is uploaded to the lookaside cache again for every branch. The new note recommends making generation reproducible — Packit already checks the lookaside cache by content hash before uploading, so byte-identical archives are not uploaded again.

Changes

• docs/configuration/examples.md: a note under "Custom archive creation for release syncing" explaining that post-upstream-clone and pre-sync run once per target branch processed by the release-sync loop, that non-reproducible generation (changing timestamps, randomness) changes the archive hash per run and triggers another lookaside upload per branch, and that reproducible generation lets Packit's existing content-hash lookaside check skip the re-upload.

Heads-up: this branch lives in an organization-owned fork, and GitHub doesn't let maintainers push to those. If anything needs changing, just say so here and I'll make the change on this branch right away.
