[FEATURE REQUEST] Use the project's WIKI to share results for each Ruby version with latest CI results

Currently, the results are in the README file, but all numbers are from one specific ruby version. Trying to add information for more rubies can make the README a mess and super large to follow.

Another source for the benchmark results is the result of CI runs which shows up-to-date and more rubies, but it's not formatted for readability, it's just the output of the rake command which is not ideal.

Maybe another option is to use the Wiki of the project creating one page with the results for each Ruby that's tested, and then use a github action to update the results there so each page is always automatically updated with the latest results from CI.

I've never done this but I think it's possible, there's this action for example that creates a Wiki page given a markdown file https://github.com/Decathlon/wiki-page-creator-action. So I understand it's possible to create/edit Wiki pages if we can output the benchmark results as a .md file using the github API.

This would help finding benchmarks relevant to the Ruby version the user is using, since different ruby versions may add new optimizations to some of the code variants and old Ruby benchmarks would be inaccurate.
