Is your feature related to a problem?

Refer to Bacon: https://github.com/crisidev/bacon-ls?tab=readme-ov-file#manual Refer to Lazyvim: https://github.com/LazyVim/LazyVim/blob/main/lua/lazyvim/plugins/extras/lang/rust.lua

Describe the new feature

Baconls is faster than rust-analyzer in analysis. I hope it can be supported.

This shouldnt be added to the rust pack. It can be its own pack if needed

Tried to add this to a bacon pack, but didnt get it to work.
