Add Perry to important public benchmark projects

[paulocoghi]

Adding Perry to important public benchmarks (below) can give valuable feedback for both Perry itself (e.g.: what it can improve) as well as give more visibility to it from potential users.

The ones I recommend:

LangArena

• site: https://kostya.github.io/LangArena/
• repo: https://github.com/kostya/LangArena

Web Frameworks Benchmark

• site: https://web-frameworks-benchmark.vercel.app/result
• repo: https://github.com/the-benchmarker/web-frameworks

TechEmpower Benchmarks
It seems to be archived, but testing locally for a comparison could still be valuable, to see how it performs related to JustJS (the JS champion so far), for example

• site: https://www.techempower.com/benchmarks/
• repo: https://github.com/TechEmpower/FrameworkBenchmarks

Programming Languages Benchmark
