            :crown: **Automated Post-Release PR**

            This pull request was created automatically by the GitHub Actions workflow. It merges changes from the `main` branch into the `develop` branch after a release has been completed.

            This ensures that the `develop` branch stays up to date with all release-related changes from the `main` branch.

            ### Details
            - **Release Version**: v${{ steps.extract-version.outputs.release_version }}
            - **Related Ticket**: [${{ steps.extract-version.outputs.release_ticket_id }}](https://linear.app/rudderstack/issue/${{ steps.extract-version.outputs.release_ticket_id }})

            ---
            Please review and merge it before closing the release ticket. :rocket:
