Steps to reproduce

• https://github.com/hengyunabc/junit5-surefire-bug-demo

In pom.xml, the configuration junit.platform.launcher.interceptors.enabled does not work.

The following configuration does not take effect:

            <plugin>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>3.1.2</version>
                <configuration>
                    <properties>
                        <configurationParameters>
                            junit.platform.launcher.interceptors.enabled=true
                        </configurationParameters>
                    </properties>
                </configuration> 

 
The following configuration can work:

            <plugin>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>3.1.2</version>
                <configuration>
                    <systemPropertyVariables>
                        <junit.platform.launcher.interceptors.enabled>true</junit.platform.launcher.interceptors.enabled>
                    </systemPropertyVariables>
                </configuration> 

 
Or configuring it in the junit-platform.properties file will also work.
