Prometheus returned no PercentileCPULoader metrics with the simple strategy

[DzeCin]

Describe the bug
When running krr version 1.8.3 (the windows binary) with the simple stratey, I can get the memory recommendations but not the CPU one.
I get those logs "Prometheus returned no PercentileCPULoader metrics with the simple strategy".
On the version 1.4.1, the cpu recommendations (and the memory one) work.

I have all the requested metrics.

To Reproduce
Steps to reproduce the behavior:

1. Open powershell
2. Port forward prometheus svc : kubectl port-forward -n monitoring svc/prometheus-server 80:80
3. Run .\krr.exe simple -p http://localhost:80 --memory_buffer_percentage=5
4. Logs such as "Prometheus returned no PercentileCPULoader metrics for Deployment" appear
5. Get this table:

Expected behavior
I expect that the CPU requests and limits are caclulated
