@MrSubidubi could you review it? 🙇

[MrSubidubi]

Thanks for this!

Could you elaborate why we could not add this to the existing Ruby extension? While we do not do this for all languages, we tend to have plenty of Ruby language servers there already and would be curios if and/or why not we cannot just add that language server to that extension also. We recently had a similar language server being added there as well.

@MrSubidubi, thanks for the quick review. I didn't know that we could add multiple LSP servers per language. Could you show me an example?

I think it would be better to keep them separate so I can add the fuzzy binary in the next version, giving the developer a better experience with this plugin (so he doesn't need to install the fuzzy binary manually to use it).
