[FIX] docker image tests do not fail if core can not start

Currently on Apache Solr 9.8.0 the cores can not boot up, because of
```
Plugin init failure for [schema.xml] fieldType "string_collated": Error loading class 'solr.ICUCollationField'
```
but the tests suite does not fail at all.

This change fixes the issue, which was caused by `prettyPrintOrExitOnError 0`
