GitHub action for "Build Testing Workflow" is using old artifacts and not building missing dependencies. This leads to broken builds that miss artifacts (like for debezium-assembly-descriptors) or does not create a fresh build for an updated debezium-core.

We have to make sure that either we stop using multi-module builds from using Maven Cache or guarantee that proper artifact caching is used.

Currently we have 2 issues: Either the build is failing because an artifact is missing in the Maven cache repo and the job doesn't build that dependency (like here with the missing `debezium-assembly-descriptors` jar. Or the build has a cached jar, but in-fact should use new updated code instead of the old cached one.
