Fix broken CI

[ahmedwaleedmalik]

What this PR does / why we need it:
After our recent upgrade for prow https://github.com/kubermatic/infra/pull/2461, prow is no longer able to resolve symlinks for the job configurations.

{"branch":"main","component":"tide","controller":"status-update","error":"failed to set up context register: failed to get presubmits: failed to read contents of directory \".prow\": open /var/tmp/gitrepo90238935/.prow/generated.yaml: no such file or directory","file":"[k8s.io/test-infra/prow/tide/status.go:436](http://k8s.io/test-infra/prow/tide/status.go:436)","func":"[k8s.io/test-infra/prow/tide.(*statusController).setStatuses.func1](http://k8s.io/test-infra/prow/tide.(*statusController).setStatuses.func1)","level":"error","msg":"getting expected status","org":"kubermatic","pr":2933,"repo":"kubeone","severity":"error","sha":"798b13eb44ed826c8fdb1946863febd9a591327a","time":"2023-10-20T09:11:05Z"}

Thanks to @xrstf we found that kubernetes/test-infra#30400 was the change that broke this. Removing the symlink in favor of copying the file(generated via code) fixes the issue.
