Script 'Sync script to Git repo' for windmill

Sync script to Git repo

Verified

This script will pull the script from the current workspace in a temporary folder, then commit it to the remote Git repository and push it. Only the script-related file will be pushed, nothing else. It takes as input the git_repository resource containing the repository URL, the script path, and the commit message to use for the commit. All params are mandatory.
