Remove duplicate integration test version output (#11360)

The TestSuiteOrdering static block was printing Maven version information
every time the class was loaded, which happened multiple times:
- Once from the outer Maven process (showing incorrect version)
- Multiple times from forked JVMs (showing correct but redundant version)

This change removes the console output while preserving essential functionality:
- Still clears system properties for test isolation
- Still sets maven.version system property (needed by some tests)
- Still writes version info to target/info.txt for debugging

Fixes the confusing duplicate output during integration test execution.
