Fix timing monitoring histograms for ITk TrigInDetValidation ART tests (EFTRACK-463)
Currently, the timing histograms for the ITk trigger ART tests are setup with x-axis ranges being too small, leading to many entries in overflow for certain situations (e.g fullscan chains when running on ttbar + 200 PU ITk RDO). This small change fixes the issue by sending the correct signature name to be checked against when setting up the monitoring. This only impacts the monitoring for ITk jobs, but targetting 24.0 to keep configurations in step. Changes will be eventually swept to main.
This work for running FTF with ITk in the trigger is tracked by EFTRACK-463
