feat(ci): enhance publishing targets and update configuration

This update introduces a new mechanism for handling multiple publish
targets when uploading artifacts. It refines the configuration by
parsing legacy targets from environment variables and allows for
dynamic bucket and directory management during the publishing process.

- Added support for multiple publish targets from environment variables
- Refactored artifact upload logic to improve maintainability
- Updated tauri configuration to include new endpoint for latest.json
