Update NoGuavaRefaster expected output for upstream static-import change

The 2026-07-20 openrewrite/rewrite snapshot changed NoGuavaRefaster so that
Preconditions.checkNotNull(obj, description) now migrates to
requireNonNull(obj, valueOf(description)) with a static import of
java.lang.String.valueOf, rather than String.valueOf(description).

Aligns the expected output in
preconditionsCheckNotNullToObjectsRequireNonNullTwoArgumentsSecondObject
with current behavior.
