fix: Fixed IntelliJ testing to work again.

The testing in IntelliJ stopped working after the commit 954a9be, which added `testRuntimeOnly(org.junit.platform:junit-platform-launcher:1.10.2)`.

It should have been version 1.9.2, which is compatible with the versions we are using. It still worked in Gradle Wrapper however.
