[2.x] React to Compressor changes from core from #9262 (opensearch-pr…

…oject#3221)

### Description

Reacting to changes from the backport of
opensearch-project/OpenSearch#9262.

This reason the main branch of Security is not encountering these errors
is because the affected class was removed in
opensearch-project#2900 and the change
has not been backported yet.

@willyborankin are you planning to backport
opensearch-project#2900?
