log file with a different instance root directory

[BenediktMeierUIT]

What steps does it take to reproduce the issue?
If you have a different instance root, you cannot execute the commands as you describe. (https://guides.dataverse.org/en/5.14/admin/metadataexport.html#batch-exports-through-the-api)
Because the log directory has been permanently programmed.
For example here:

dataverse/src/main/java/edu/harvard/iq/dataverse/DatasetServiceBean.java

Line 702 in ec1b174

String logFileName = "../logs" + File.separator + "export_" + logTimestamp + ".log";

(I have already made an improvement and I will upload it right away.)
