Add support to the Helix editor

[treeman]

1. Add it to languages.toml: https://github.com/helix-editor/helix/blob/master/languages.toml
2. Insert the queries here: https://github.com/helix-editor/helix/tree/master/runtime/queries

That would be amazing! You might have to have a separate directory for Helix queries though, since it seems that some of the nvim-treesitter queries aren't compatible with Helix, ex. @markup.strong is @markup.bold in Helix

Yes, all the highlights needs to be reworked for the specific editor. The highlight files in this repo have been made with Neovim in mind because that's what I use, but should be seen as a starting point for porting it to other editors.

And even for Neovim they're a little bit different, as nvim-treesitter manages highlights.scm themselves, which is what everyone using Neovim will probably use (unless they create their own query file).

I've been working on this since coming across this issue in the Helix repo the other day.

As I've said there, work is complete on the highlights and injections --- I'm just finishing up the languages.toml portion before I prepare a PR there.

I've noted that you're working on a pretty big rewrite, I'm happy to adapt the queries once djot and djot-inline are separated, but I figure it would still be nice for us to have current djot support in the meantime in Helix.

If you're curious about what the highlights are looking like in Helix, I've provided some screenshots in this comment on the PR.

I managed to rework the big rewrite to not be as breaking, although a few breaking changes were made. See #56 for (hopefully) a complete list of changes.

Thanks for your hard work on the rewrite! It happened to coincide quite closely with Helix merging a change to have the same precedence as Neovim in its queries. I've inverted the order and everything should now be in a state that can be merged and will be easy to maintain over time since it's closer to the queries you maintain in this repo as well 😄
