- Refactored `TriggerInvokeResponse` to use `Mapping[str, Any]` for event representation.
- Renamed `properties` to `variables` in the `Event` class for clarity and updated the description accordingly.
- Expanded the event options in the GitHub trigger configuration to allow selection of all events.
- Removed the deprecated `issue_comment` trigger implementation and its associated files.
- Bumped version in `manifest.yaml` to 0.0.9 to reflect these changes.
These updates improve the flexibility and clarity of the GitHub trigger integration, allowing for a broader range of event handling.
