Docs: Add latency data to docs/benchmarks

Summary

The current docs page only reports Requests per second, which is definitely a very important metric for web frameworks. However, latency is also very important!

The current benchmarks suite already reports the latency details - it will be really nice if the results can be included in the docs.

Why not just let the reader run the benchmarks themselves?

• running the benchmarks takes a long time
• it doesn't work sometimes - I got several errors while running the benchmarks suite as-is
