Add more benchmarks in ArkScript

[SuperFola]

We currently only have Ackermann Péter function, Fibonacci, some quicksort... but we could always use a little more benchmarks!

Don't hesitate to submit benchmarks in

• Java
• Javascript
• Python
• Ruby
• Perl
• C++
• Lua
• ArkScript
• any other mainstream language

No need to provide a benchmark for every language, even if you provide a single Java benchmark, it's fine, we can translate it in the other languages later!

See https://github.com/wren-lang/wren/tree/main/test/benchmark for ideas

Might need to update the website if we add a new benchmark while much older ones exist, so that it doesn't break the UI.
