ATR-25035: Use update_inputs script to grab files for Rulebook test
FYI @tvazquez
The update to the Rulebook to read the HLTMonitoring json and set the Express Stream rates was not accompanied by an update to the setup script for the ART Rulebook test. This change should help prevent future inconsistencies by using the RB's own update_inputs.sh
script to link all relevant files.
