Map one more varargs diagnostic

Cases like:
```
!ENTRY org.eclipse.jdt.core 4 0 2025-01-22 10:50:27.539
!MESSAGE Could not accurately convert diagnostic
(compiler.warn.varargs.unsafe.use.varargs.param)
/home/akurtakov/git/eclipse.platform.ui/tests/org.eclipse.jface.tests.databinding/src/org/eclipse/core/tests/databinding/observable/list/ListDiffTest.java:148:
warning: [varargs] Varargs method could cause heap pollution from
non-reifiable varargs parameter differences
		return Diffs.createListDiff(differences);
```
should be properly mapped now.
