Remove unsupported versions from CI.

Description

Remove unsupported python version from CI workflows.

Issues Resolved

Fix CI failures, see job run for example and test run logs. opensearch-py starting from version 2.0.0 requires certifi>=2022.12.07 which is not released for old python versions.
