Remove duplicate integration test version output

[gnodet]

Problem

When running integration tests, we see duplicate and confusing output like:

[INFO] [stdout] Running integration tests for Maven 4.0.0-rc-4
[INFO] [stdout]         using Maven executable: mvn
[INFO] [stdout]         with verifier.forkMode: AUTO
[INFO] [stdout] Running integration tests for Maven 4.1.0-SNAPSHOT
[INFO] [stdout]         using Maven executable: mvn
[INFO] [stdout]         with verifier.forkMode: AUTO
[INFO] [stdout] Running integration tests for Maven 4.1.0-SNAPSHOT
[INFO] [stdout]         using Maven executable: mvn
[INFO] [stdout]         with verifier.forkMode: AUTO

The first line shows the wrong version (from the outer Maven process), and the subsequent lines are redundant output from forked JVMs.

Root Cause

The TestSuiteOrdering static block was printing Maven version information every time the class was loaded, which happens:

1. Once in the outer Maven process (showing incorrect version 4.0.0-rc-4)
2. Multiple times in forked JVMs (showing correct version 4.1.0-SNAPSHOT but redundantly)

Solution

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 like MavenITmng3652UserAgentHeaderTest)
• ✅ Still writes version info to target/info.txt for debugging
• ❌ Removes the problematic console output

Benefits

• Eliminates confusing duplicate output during integration test execution
• Fixes incorrect version display from outer Maven process
• Maintains all functionality that tests actually depend on
• Simpler, cleaner code

Testing

The change preserves all existing functionality while removing only the problematic console output. Integration tests will continue to work as before, just without the duplicate version messages.
