Use version pattern in noDependencyManagementSection test (#7475)

ChangeDependencyGroupIdAndArtifactIdTest.noDependencyManagementSection
hardcoded the post-recipe junit-jupiter version as 5.14.3, but the
recipe resolves "5.x" against Maven Central at runtime. Every new
junit-jupiter 5.x patch release breaks CI for every PR until someone
bumps the literal. The most recent break is 5.14.4, published earlier
today.

Switch the assertion to a regex pattern matching any 5.x.x release,
following the convention established in #6799 / #6856.
