fix(api-server): skip display-name label for service insight

[Icarus9913]

This API would list the SeviceInsight resources with k8s mode, in which the common method GetLabels would be called and supplement the display-name for the Meta.

So, let's just add a mapper function to remove that label in the API-Server component.

Checklist prior to review

• Link to relevant issue as well as docs and UI issues -- close Skip display name ServiceInsight #9729
• This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as a image registry) and it will work on Windows, system specific functions like syscall.Mkfifo have equivalent implementation on the other OS --
• Tests (Unit test, E2E tests, manual test on universal and k8s) --
  • Don't forget ci/ labels to run additional/fewer tests
• Do you need to update UPGRADE.md? --
• Does it need to be backported according to the backporting policy? (this GH action will add "backport" label based on these file globs, if you want to prevent it from adding the "backport" label use no-backport-autolabel label) --
