LOGGING-185: Fix failing tests (#180)

* Fix names of deployed artifacts

We remove the obsolete `finalName` property and fix the Maven Failsafe
executions.

* Fix failing tests

* Reenable integration tests

* Disable SecurityManager tests on Java 21

* Simplify build workflow

* Set `fail-fast` to false

* Fix NPEs caused by `String.trim()`

* Span a different JVM per test case
