Adapted the processes that needed to read conditions in Boole for VP simulation, VPDepositCreator and VPDigitCreator. Also requires Detector!374 and lhcb-conddb/lhcb-conditions-database!60 (merged) which sets the condition paths and condition YAML respectively.
Currently marked as draft as the FT also added a private Sim branch which this change is not compatible with. If we are happy to break the nightly tests then this can be submitted (will need new reference files for several tests).
