Don't require adding the https port in additionalExposedPorts when https is enabled

[cccs-nik]

The changes below are a subset of the changes seen in #300 but the PR hasn't seen activity in over a month so I thought it might make sense to create this small PR. The changes in this PR are also independent of the other changes proposed by #300 to support internal TLS.

See the test failures:

 Error: INSTALLATION FAILED: 2 errors occurred:
Error: failed installing charts: failed processing charts
	* Service "trino-9qjh10dbwo-trino" is invalid: [spec.ports[3].name: Duplicate value: "https", spec.ports[3]: Duplicate value: core.ServicePort{Name:"", Protocol:"TCP", AppProtocol:(*string)(nil), Port:8443, TargetPort:intstr.IntOrString{Type:0, IntVal:0, StrVal:""}, NodePort:0}]
	* Deployment.apps "trino-9qjh10dbwo-trino-coordinator" is invalid: spec.template.spec.containers[0].ports[4].name: Duplicate value: "https"

Thanks for the heads-up @nineinchnick, the port was indeed duplicated from additionalExposedPorts in the test file. I removed it and it looks good now.
