output bug: missing spaces

https://git.slub-dresden.de/digital-preservation/mediaconch_plugin4rosetta/-/blob/master/java/org/slub/rosetta/dps/repository/plugin/SLUBMatroskaFFV1FormatValidationPlugin.java#L84

leads to erroneous outputs like:

2023-07-31 08:43:11,431 INFO  [org.slub.rosetta.dps.repository.plugin.SLUBMatroskaFFV1FormatValidationPlugin] (GENERIC_REP_Q Queue Job Receiver 89) [] SLUBMatroskaFFV1FormatValidationPlgin instantiated with mediaconch binary=/usr/bin/mediaconchcfg (current)=/etc/mediaconch/current_slub.cfgcfg (upcoming)=/etc/mediaconch/upcoming_slub.cfg

The expected output would contain more spaces, like

2023-07-31 08:43:11,431 INFO  [org.slub.rosetta.dps.repository.plugin.SLUBMatroskaFFV1FormatValidationPlugin] (GENERIC_REP_Q Queue Job Receiver 89) [] SLUBMatroskaFFV1FormatValidationPlgin instantiated with mediaconch binary=/usr/bin/mediaconch cfg (current)=/etc/mediaconch/current_slub.cfg cfg (upcoming)=/etc/mediaconch/upcoming_slub.cfg
