Automated changelog syncs from main to release branches

Problem Statement

We're using automation that backports PRs from main to release branches if we label them with backport release/x.x.x. If a change set includes changelog entries, it fails in most cases to run successfully (like here). That forces us to resolve the conflict and do the backport manually.

The goal of this issue is to ensure there's automation that synchronizes CHANGELOG.md from main to all feature branches so the aforementioned conflicts are less frequent.

Proposed Solution

Use a GH workflow triggered by changes in the CHANGELOG.md on main that will propagate the changes to all feature branches (release/x.x.x).

https:/marketplace/actions/repo-file-sync-action seems to be capable of achieving something like that quite easily (sample config: https:/marketplace/actions/repo-file-sync-action#syncing-branches)

Additional information

No response

Acceptance Criteria

• CHANGELOG.md on every feature branch is synchronized with main
