[MSHARED-1140] Simplify Maven version extraction in the forked launcher

[jira-importer]

Michael Osipov opened MSHARED-1140 and commented

The approach from org.apache.maven.shared.verifier.ForkedLauncher.extractMavenVersion(List<String>) is way too complex. Especially for that use case I have modeled many years ago:

D:\Entwicklung\Projekte> mvn -v -q
3.8.6 

Done.

Crap...I thought I have added it much much earlier. Then we'd need to stall this until we require Maven 3.8.x.
