ref(test): Disable kotest classpath autoscan (#2164)

This change reduces test execution time by about 1 min (30%) on my
machine.

Since the update to kotest 5.9 the following warning gets printed during
tests:
Warning: Kotest autoscan is enabled. This means Kotest will scan the classpath for extensions that are annotated with @AutoScan. To avoid this startup cost, disable autoscan by setting the system property 'kotest.framework.classpath.scanning.autoscan.disable=true'. In 6.0 this value will default to true. For further details see https://kotest.io/docs/next/framework/project-config.html#runtime-detection
