[CNSL-1935] Add automated release PR workflow

Added GitHub Actions workflow that automatically creates release PRs
when pending-deploy-* branches are merged to main. The workflow uses the
reusable workflow from cockroachdb/actions and updates the version number
in CHANGELOG.md, go.mod, config files, and documentation.
