forceStdout and -q prints more than expected in Maven 4.0.0-rc6

[khmarbaise]

Affected version

3.5.2

Bug description

If you use maven-help-plugin in combination with maven-4.0.0-rc-6 for example to get information about the maven.compiler.release property:

$> RESULT=$(mvn help:evaluate -Dexpression=maven.compiler.release -q -DforceStdout)
$> echo $RESULT
[INFO] [stdout] 23

That means the the expected value of RESULT should be 23 (With Maven3) but with Maven 4.0.0-rc-6 is [INFO] [stdout] 23 which beaks scripting.
