feat: add publishing logic for lla_plugin_utils in release workflow

- Implemented checks to publish the lla_plugin_utils package if the specified version is not already published.
- Added echo statements to inform about the publishing status of lla_plugin_utils.
- Included a sleep command to allow for crates.io indexing after publishing.
