# get_repo is a function to download a specific path from a GitHub repository, package it with Helm, and move the package to the 'repo' directory.
# It takes four parameters:
#   - repo: The GitHub repository from which to download. It should be in the format 'username/repo'.
#   - path: The path within the repository to download.
#   - strip: The number of leading components from file names to strip. This is passed to the '--strip' option of 'tar'.
#   - branch: The branch of the repository to download. If not provided, it defaults to 'HEAD'.
#
# The function first checks if the 'branch' parameter is provided. If not, it sets 'branch' to 'HEAD'.
# It then downloads the specified path from the repository and extracts it into the 'charts' directory.
# After that, it packages the downloaded files with Helm and moves the package to the 'repo' directory.
