This pull request (#208) introduces the GithubCommentModule, a new TypeScript class designed to automate the posting of GitHub comments based on specific results. Key functionalities include:

1. Configuration Management: The module loads its configuration from GithubCommentConfiguration, allowing customization of comment behaviors through the ubiquibot-config.
2. HTML Encoding: Utilizes jsdom to safely encode special characters in comment strings, ensuring that comments render correctly on GitHub.
3. Content Generation: The getBodyContent method constructs the comment body, supporting both full and truncated content based on length constraints. It intelligently includes or excludes specific data points to adhere to GitHub's comment size limits.
4. Metadata Integration: Adds structured metadata to comments using helper functions, embedding information like workflow URLs to provide context and traceability.
5. GitHub API Interaction: Leverages the @octokit/rest package to interact with GitHub APIs, enabling actions like posting comments and handling workflow events.
6. Logging and Error Handling: Incorporates custom logging via @ubiquity-dao/ubiquibot-logger to track operations and potential issues, enhancing maintainability and debugging capabilities.
7. Environment Management: Manages environment variables securely with dotenv, ensuring sensitive information like COMMENT_ID is handled appropriately.

Overall, this module enhances the repository's ability to programmatically manage GitHub comments, streamlining processes like notifying contributors, reporting statuses, and integrating AI-driven functionalities.
