Configure a used repository template to respect export-ignored paths

configure-repository.yml

# When using the Repository Template feature on GitHub, it does not follow the same rules as Composer create-project or ZIP downloads.
# For this reason, we have this script which will configure the repository the first time it is set up in order to normalize it.
