Root cause:
Boto3 has removed six in its later versions: boto/botocore#2806. However, the cli plugin is still utilizing a stale version. Furthermore, opensearch-py uses boto3 version 1.28 or higher. https://github.com/opensearch-project/opensearch-py/blob/94e33c68990fc62906f2dc7239c1eeb2eae3b79e/samples/pyproject.toml#L12

Verification:
This change is tested on sql plugin where all CI passed opensearch-project/sql#2499
