Pin maven-jar-plugin 3.5.1 in modular IT fixtures

[slawekjaranowski]

The windows-latest jdk-11 CI cell fails for every PR since Maven 3.10.0-rc-1 became the IT baseline: its super-POM pins maven-jar-plugin 3.5.0, whose plexus-archiver 4.10.4 throws an NPE
(JarToolModularJarArchiver.fixLastModifiedTimeZipEntries) when packaging modular JARs on Windows with JDK < 14 (no 'jar --date'; POSIX attribute view is null on Windows). Details and validation: apache/maven-jar-plugin#555

maven-jar-plugin 3.5.1 (released 2026-07-22) ships plexus-archiver 4.12.0 with the fix. Pin 3.5.1 explicitly in the four affected modular fixtures so they stop depending on the super-POM's jar-plugin version.

Verified locally under Maven 3.10.0-rc-1: Surefire1733JUnit4IT, Surefire1733TestngIT, Surefire2190JUnit4IT and
Surefire1993JpmsProvidingModulesIT green; fixture logs confirm maven-jar-plugin:3.5.1:jar executed.

Same approach as the merged #3398 pin, extended to the modular-JAR IT fixtures that carry their own POMs (so they didn't inherit the pin). Correct fix for the plexus-archiver 4.10.4 NPE (jar#555) on Windows JDK<14. LGTM — thanks @slawekjaranowski. (Approving on the logic; the windows-latest jdk-11 cell is the one to watch as CI finishes.)
