refactor(trigger): update plugin and trigger entity structures

- Removed unnecessary newline in `TriggerPluginNode` class for consistency.
- Made `provider` in `TriggerIdentity` optional to enhance flexibility.
- Added `trigger` field to `PluginDeclaration` and updated `PluginCategory` to include `Trigger`, improving the integration of trigger functionalities within the plugin architecture.

These changes streamline the entity definitions and enhance the overall structure of the trigger and plugin components.
