What type of PR is this?

/kind bug

What this PR does / why we need it:

I've encountered the below error when prometheus is enabled but kube-scheduler is disabled. Specifically, I was trying to enable prometheus for kube-scheduler-simulator so this issue is reproducible by setting options.prometheusPort to 9090 in https://github.com/kubernetes-sigs/kube-scheduler-simulator/blob/6cce7f41e06d3a419188f689264387d937c8b460/kwok.yaml.

{"time":"2024-09-17T01:40:26.594777384Z","level":"ERROR","source":{"function":"main.main","file":"/workspace/cmd/kwokctl/main.go","line":54},"msg":"Execute exit","err":"failed to start cluster \"kwok-kwok\": broken links dependency detected: [prometheus]"}

Hi @chotiwat. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
