ci: remove back-merge main to develop step

Remove the back-merge step that automatically synced changes from the main branch
to develop after a release. This eliminates the complex automatic conflict resolution
logic that tried to merge or force-resolve merge conflicts.

Simplifies the release workflow by avoiding potentially risky forced pushes to
develop and reduces complexity in the CI process.
