[cetic/swaggerui] nodePort value in chart not adjustable

[javajon]

Describe the bug
Chart parameters in readme indicate the default for the nodeP:ort can be set to alternate value:

service.nodePort | Port where the service is reachable | 30245

However, the Service.yaml template lacks that setting.

Version of Helm and Kubernetes:
v3, v1.18

What happened:

NodePort is not set when applying --set service.nodePort=31234

What you expected to happen:

nodePort value to be set either chart value.yaml default or overridden value. The default should be nil, not 30245 as suggested since the default behavior is to allow Kubernetes to find a free one.

How to reproduce it (as minimally and precisely as possible):

Install the chart with --set service.nodePort=31234 and notice the nodePort value is not set.
