(fix ci?) docker/conf/deposit: Add missing storage entry
Recently, for the latest deposit migration, the script needed a storage entry in its configuration.
If it's not present, the script should fail.
So that may be the reason of the current build failure (that timeouts when trying to discuss with the deposit). If my hypothesis is correct, the deposit service should not have started at all.
