Fix folder permissions issue

[eak12913]

This fix addresses an issue where terragrunt throws an issue when calling functions like get_repo_root which uses git rev-parse under the hood and gets a permissions error like:

git rev-parse --show-toplevel
fatal: detected dubious ownership in repository at '/github/workspace/infrastructure-live'
To add an exception for this directory, call:

        git config --global --add safe.directory /github/workspace/infrastructure-live
