Subject: [PATCH] Override xtext-dev-bom's junit-platform pin to match
 junit.version

xtext-dev-bom (imported above junit-bom in dependencyManagement) pins
junit-platform-commons/junit-platform-engine to its own
junit-platform-version (1.10.2), and since it's imported first, that
pin wins over junit-bom's. Bumping junit.version to 6.1.3 left
junit-jupiter-engine:6.1.3 running against junit-platform-engine:1.10.2,
which predates the closeAutoCloseables() API jupiter-engine 6.1.3 calls:

  java.lang.NoSuchMethodError: 'org.junit.platform.engine.support.store.NamespacedHierarchicalStore$CloseAction org.junit.platform.engine.support.store.NamespacedHierarchicalStore$CloseAction.closeAutoCloseables()'

Fix: add explicit dependencyManagement entries for junit-platform-commons
and junit-platform-engine at ${junit.version}, mirroring the existing
junit-jupiter-api/junit-jupiter-engine overrides right above them.

Verified: `mvn dependency:tree` now resolves junit-platform-* to 6.1.3,
and `mvn test` passes all 94 tests (previously failed with the error
above).
