feat(trigger): enhance GitHub trigger with multiple event selection and dynamic parameter options

- Updated `IssueCommentTrigger` and `GithubProvider` to support multiple event selections for GitHub triggers.
- Introduced a new `multiple` field in the trigger parameters to allow users to select multiple events.
- Implemented dynamic fetching of repository options based on OAuth credentials.
- Bumped version in `manifest.yaml` to 0.0.7 to reflect these enhancements.

This update improves the flexibility and usability of the GitHub trigger integration.
