This commit introduces a new feature that allows the AI Code Bot to learn from a given repository. The bot can now clone a repository, load its documents, and store them in a local vector store for future use. This will enhance the bot's ability to provide contextually relevant suggestions and responses.

Additionally, this commit includes the necessary updates to the configuration and helper functions to support this new feature. The requirements have also been updated to include the necessary dependencies.

Lastly, a new test case has been added to ensure the correct parsing of GitHub URLs. 🧪

Resolves #47

Updated the unlink method for Path objects in `aicodebot/cli.py` and `tests/test_cli.py` for better readability and consistency. Now using `Path(temp_file_name).unlink()` instead of `Path.unlink(temp_file_name)`. 🔄📁
