Implement repository template creation functionality for GitHub bot

- Add CreateRepositoryFromTemplate method to GitHubStorage class
- Implement CreateRepositoryFromTemplateTrigger for handling template creation requests
- Support for hello world, console app, and library templates
- Add usage examples and documentation
- Register new trigger in main program

This allows users to create repositories from templates by opening issues with specific titles
and specifying repository names in the issue body.
