Enhance docstrings across the codebase to improve documentation of function arguments, return values, and exceptions raised. #111

One of the potential issues in the provided codebase is the absence of detailed docstrings in many functions and methods. While some functions do have brief descriptions, they often lack detailed information about arguments, return values, and exceptions raised. This can make the code difficult to understand and maintain, especially for newcomers or contributors. Enhancing the docstrings to provide more comprehensive documentation would improve the readability and usability of the codebase. For example, the setup_repository function in the services/github/__init__.py module could benefit from such enhancements.

Here is a suggested enhancement for the setup_repository function's docstring:

def setup_repository(repo: str, branch_name: str = "main"):
    """
    Set up the repository to point to a specific branch.

    This function checks if the given repository exists in the local file system. If it doesn't exist, 
    the function clones it from GitHub. If it does exist, the function pulls the latest changes from 
    the remote repository. The function then checks out the specified branch.

    Args:
        repo (str): The name of the repository in the format 'owner/repo'.
        branch_name (str): The branch to check out. Defaults to 'main'.

    Raises:
        exceptions.GitHubRepoNotFoundException: If the repository is invalid or not found.
    """
    # リポジトリが存在するか確認する
    if not github_utils.exists_repo(DEFAULT_PATH, repo):
        # リポジトリが存在しない場合はcloneする
        clone_repository(repo)
    else:
        # リポジトリが存在する場合はpullする
        branch = get_branch(repo)
        default_branch = get_default_branch(repo)
        if branch != default_branch:
            # ブランチが異なる場合はデフォルトブランチに戻す
            checkout_branch(repo, default_branch)
        pull_repository(repo)
    # リポジトリのブランチを指定する
    checkout_branch(repo, branch_name)

Adding such detailed docstrings throughout the codebase can significantly improve code maintainability and collaborative development.
