Try and give more helpful error message for bad surefire version

[holly-cummins]

See discussion around #34681 (comment)

Detecting surefire is relatively easy, but I couldn't find a great way to detect the version. The best I could do was look at the name of the surefire booter. For Surefire 3.x it ends in _3, such as

surefire.real.class.path:/Users/holly/Code/quarkus/quarkus/integration-tests/gradle/target/surefire/surefirebooter-20250422184338999_3.jar

For Surefire 2 it's a random number, such as

surefire.real.class.path:/Users/holly/Downloads/code-with-quarkus/target/surefire/surefirebooter3233894128258247821.jar

I wouldn't want to do such fragile detection for something important, but since it's just enhancing an error message it should be ok.

Example (from a local test) output with new message:

java.lang.RuntimeException: The test class class org.acme.GreetingResourceTest should have been loaded with a QuarkusClassLoader, but instead it was loaded with jdk.internal.loader.ClassLoaders$AppClassLoader@2c854dc5. Is the version of the Surefire plugin at least 3.x?
