ci(lint): don't accidentally append to non-zero length slices

[alingse]

Checklist prior to review

I was running github actions to run linter makezero for top github golang repos.

see issues alingse/go-linter-runner#1

and the github actions output https://github.com/alingse/go-linter-runner/actions/runs/9242968813/job/25426482280

====================================================================================================
append to slice `orderedTags` with non-zero initialized length at https://github.com/kumahq/kuma/blob/master/api/common/v1alpha1/ref.go#L104:17
append to slice `combinedResources` with non-zero initialized length at https://github.com/kumahq/kuma/blob/master/app/kumactl/cmd/install/install_observability.go#L43:24

• Link to relevant issue as well as docs and UI issues --
• 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) --

Hi! Thanks for your contribution, please add this linter to .golangci.yml - https://github.com/kumahq/kuma/blob/master/.golangci.yml#L2 - I would've done it myself but you did not allow maintainers to modify this PR.

@slonka I have add makezero to .golangci.yaml ( but it may report some bad case in future)
