I would like to get a few more of these up and running, I'll see what others remain which are more low hanging fruit (Already on version 0.20 of tree-sitter and already expose the highlight query).

One other thing I would like to address is whether or not we wish to put a feature flag on these? Not sure how large all of these + build time impact this would have for lapce. Something to think about...

Cheers, I am really enjoying this editor!
