ruff server add setup guide for helix editor

[bluthej]

I'm very excited about the new Ruff LSP, and I would like to try it out in Helix, my editor of choice :)

I did not have a ton of time to look at the config yet but I started playing around with it and I believe the config should start with something like this:

[language-server.ruff]
command = "ruff"
args = ["server", "--preview"]

Then the language server should be added alongside whatever other server you like to use (guess which one I use):

[[language]]
name = "python"
language-servers = ["ruff", "pylsp"]

I haven't really had a ton of success for now with server-specific configs (like the ones in the neovim setup), so a dedicated setup guide would be much appreciated :)
Or really any pointer on the setup!
