app.kubernetes.io/version Pod label always points to .Chart.AppVersion regardless whats set in values

[pmalek]

Problem statement

kong chart's Pods are deployed with a set of labels, among those there is app.kubernetes.io/version, which has its value always set to .Chart.AppVersion.

This is incorrect because one might change the image tag e.g. via image.tag which will result in Gateway Pods to have app.kubernetes.io/version label set to whatever's defined in the chart but have the tag set to whatever image.tag.

Acceptance criteria

• Decide whether we'd like to keep this Pod label or remove it
  • If the decision was to keep it, then make it consistent with whatever's set via e.g. image.tag and/or image.effectiveSemver
