One of the test cases purported to test the appending of unique values to an existing list but the list of unique values to be appended was randomly generated and would occasionally contain values already in the list (see example test seed below). This fix ensures that the list of unique values never contains any values in the existing list.
Example of a test seed that would fail:
./gradlew ':modules:ingest-common:test' --tests "org.elasticsearch.ingest.common.AppendProcessorTests.testAppendingToListWithDuplicatesDisallowed" -Dtests.seed=AC5D435485DE7219
Backport of #62385
