Invalid OpenAPI port for RDDMS

The port exposed as part of the openAPI UI of the RDDMS needs to be the gateway port (443) and not the internal container port (8003). An environment variable was recently added to open-etp-client to be able to handle it. The new variable has been added to devops\azure\reservoir.values.yaml inside open-etp-client but also needs to be added to these helm charts as well.

The suggested fix is to add

OPEN_API_PORT: "443"

to osdu-ddms\standard-ddms\reservoir.osdu.values.yaml line 48
