This commit simply adds github-actions[bot] (a bot used in the
woocommerce-blocks repository) to the list of users ignored
by the bin/contributors.sh script.
Now that woocommerce-rest-api was merged back into the WC core
repository, we don't need to check contributions in the depreacted
woocommerce-rest-api repository.
