Fix Python script file path passing in localize_yml_file

The Python script wasn't receiving the file path correctly because heredoc syntax doesn't support command-line arguments the way it was written. Changed to use environment variable COMPOSE_FILE_PATH instead.

This fixes the SyntaxError that occurred during deployment where Python was trying to parse YAML as Python code.
