Fix Document GET with DLS terms query (opensearch-project#3136)

### Description

Fixes an error on document retrieval for users that are mapped to roles
with DLS rules including a terms query. The bug was introduced by a
change in Lucene and reported on Slack
[here](https://opensearch.slack.com/archives/C0539F41Z5X/p1690714779140659).
This fix adds a test to catch an error like this at build time and
assert the intended behavior.
