Pruning is not triggered for `VolumeFreeSpace`

[rubo]

Pruning was not triggered when the storage space dropped to below the specified threshold.

Steps to Reproduce The user used the following configuration:

--config mainnet \
--datadir /var/lib/nethermind \
--Sync.SnapSync true \
--Sync.AncientBodiesBarrier 11052984 \
--Sync.AncientReceiptsBarrier 11052984 \
--JsonRpc.JwtSecretFile /var/lib/jwtsecret/jwt.hex
--JsonRpc.AdditionalRpcUrls http://127.0.0.1:1337|http|admin \
--JsonRpc.EnginePort 8551 \
--JsonRpc.EngineHost 127.0.0.1 \
--Pruning.FullPruningCompletionBehavior AlwaysShutdown \
--Pruning.FullPruningTrigger=VolumeFreeSpace \
--Pruning.FullPruningThresholdMb=330000 \
--Pruning.FullPruningMaxDegreeOfParallelism 2 \
--Pruning.FullPruningMemoryBudgetMb=4096

Actual behavior Pruning was not triggered even when the free disk space dropped to 227 GB.

Expected behavior Pruning should be triggered when the free disk space drops to ~320 GB (330k MB) according to the Pruning.FullPruningThresholdMb=330000 flag.
