Canonical benchmarks for default algo dev are well documented and repeatable

[kfswain]

A follow-up issue for #967

Algo development has a dependency on the specific benchmarking to ensure repeatable behavior. This issue is to track and make sure that the canonical benchmark is well defined and repeatable. I think this may exist, but this issue would validate & make these benchmarks clear.

Additional info, GKE has internal benchmarks that run nightly, this issue would ensure that those nightly runs use the same benchmarks that we publish.

@kaushikmitr Can we make the GKE internal benchmark nightly run results public?

@liu-cong This link should be publicly accessible. https://lookerstudio.google.com/c/u/0/reporting/c7ceeda6-6d5e-4688-bcad-acd076acfba6/page/p_d1f0zus4sd/edit

@kaushikmitr Thanks! Can you update the performance page with the dashboard link? Thanks! https://gateway-api-inference-extension.sigs.k8s.io/performance/benchmark/
