# This class represents an action that clones and loads a repository from a
# given URL. The action expects a repository URL as input and returns a
# Repository object containing the repository's data.
#
# Example usage:
#   repository = Actions::CloneAndLoadRepository.call(
#     repository_url: "https://github.com/ljuti/roseflow.git"
#   )
