OpenSearch TLS Version

Ensure OpenSearch domain is using the latest security policy to only allow TLS v1.2

OpenSearch domains should be configured to enforce TLS version 1.2 for all clients to ensure encryption of data in transit with updated features.

Update OpenSearch domain to set TLSSecurityPolicy to contain TLS version 1.2.
