fix(ng-dev): remove renovate target label update during release

The logic to update the renovate config during the release to switch the target labels from `target: rc` to `target: patch` has been removed. Instead, a static `target: automation` label is added to the default renovate preset.

This simplifies the release process by removing the need to update the renovate config during the release.
