fix(trigger): improve error handling in DraftWorkflowTriggerNodeApi and update input class naming

- Removed specific exception handling for ValueError and PluginInvokeError in `DraftWorkflowTriggerNodeApi`, allowing a more general exception to be raised.
- Renamed `PluginTriggerInput` to `TriggerEventInput` in `TriggerEventNodeData` for better clarity and consistency.
- Updated validation logic in `TriggerEventInput` to ensure correct type checks for input values.
