`NoClassDefFoundError` when running JUnit tests with Spock

It appears that the wrong version of junit platform engine is resolved when running Spock tests from a Maven project.

Yields the following stacktrace:

:notebook: Adding an explicit dependency to `org.junit.platform:junit-platform-engine:1.10.1` workaround the issue. By default, Spock depends on version `1.9.0`

```

org.junit.platform
junit-platform-engine
1.10.1
test

```
