feat: add actor-based comment filtering to GitHub data fetching (#812)

- Introduced `include_comments_by_actor` and `exclude_comments_by_actor` inputs in action.yml to allow filtering of comments based on actor usernames.
- Updated context parsing to handle new input fields.
- Implemented `filterCommentsByActor` function to filter comments according to specified inclusion and exclusion patterns.
- Modified `fetchGitHubData` to apply actor filters when retrieving comments from pull requests and issues.
- Added comprehensive tests for the new filtering functionality.

This enhancement provides more control over which comments are processed based on the actor, improving the flexibility of the workflow.
